Terrorism
Throughout human history, there have been many threats to the security of nations. These threats have brought about
large-scale losses of life, the destruction of property, widespread illness and injury, the displacement of large numbers of
people, and devastating economic loss.
Recent technological advances and ongoing international political unrest are components of the increased risk to national
security.
Use Part 4 to learn what actions to include in your family disaster plan to prepare for and respond to terrorist threats.
When you complete Part 4, you will be able to:
• Recognize important terms.
• Take protective measures for terrorist threats.
• Know what actions to take if an event occurs.
• Identify resources for more information about terrorist threats.

General Information
about Terrorism
4.1 General Info about Terrorism Are You Ready?
148
Terrorism is the use of force or violence against persons or property in violation of
the criminal laws of the United States for purposes of intimidation, coercion, or
ransom. Terrorists often use threats to:
• Create fear among the public.
• Try to convince citizens that their government is powerless to prevent
terrorism.
• Get immediate publicity for their causes.
Acts of terrorism include threats of terrorism; assassinations; kidnappings; hijackings;
bomb scares and bombings; cyber attacks (computer-based); and the use of
chemical, biological, nuclear and radiological weapons.
High-risk targets for acts of terrorism include military and civilian government
facilities, international airports, large cities, and high-profi le landmarks. Terrorists
might also target large public gatherings, water and food supplies, utilities,
and corporate centers. Further, terrorists are capable of spreading fear by sending
explosives or chemical and biological agents through the mail.
Within the immediate area of a terrorist event, you would need to rely on police,
fi re, and other offi cials for instructions. However, you can prepare in much the
same way you would prepare for other crisis events.
The following are general guidelines:
• Be aware of your surroundings.
• Move or leave if you feel uncomfortable or if something does not seem right.
• Take precautions when traveling. Be aware of conspicuous or unusual behavior.
Do not accept packages from strangers. Do not leave luggage unattended.
You should promptly report unusual behavior, suspicious or unattended packages,
and strange devices to the police or security personnel.
• Learn where emergency exits are located in buildings you frequent. Plan how
to get out in the event of an emergency.
• Be prepared to do without services you normally depend on—electricity,
telephone, natural gas, gasoline pumps, cash registers, ATMs, and Internet
transactions.

Terrorists have frequently used explosive devices as one of their most common
weapons. Terrorists do not have to look far to fi nd out how to make explosive devices;
the information is readily available in books and other information sources.
The materials needed for an explosive device can be found in many places including
variety, hardware, and auto supply stores. Explosive devices are highly portable
using vehicles and humans as a means of transport. They are easily detonated from
remote locations or by suicide bombers.
Conventional bombs have been used to damage and destroy fi nancial, political,
social, and religious institutions. Attacks have occurred in public places and on city
streets with thousands of people around the world injured and killed.
Parcels that should make you suspicious:
• Are unexpected or from someone unfamiliar to you.
• Have no return address, or have one that can’t be verifi ed as legitimate.
• Are marked with restrictive endorsements such as “Personal,” “Confi -
dential,” or “Do not X-ray.”
• Have protruding wires or aluminum foil, strange odors, or stains.
• Show a city or state in the postmark that doesn’t match the return address.
• Are of unusual weight given their size, or are lopsided or oddly
shaped.
• Are marked with threatening language.
• Have inappropriate or unusual labeling.
• Have excessive postage or packaging material, such as masking tape
and string.
• Have misspellings of common words.
• Are addressed to someone no longer with your organization or are
otherwise outdated.
• Have incorrect titles or titles without a name.
• Are not addressed to a specifi c person.
• Have hand-written or poorly typed addressess.

• Notify the police and the building management.
If there is an explosion, you should: During an Explosion
• Get under a sturdy table or desk if things are falling around you. When they
stop falling, leave quickly, watching for obviously weakened fl oors and stairways.
As you exit from the building, be especially watchful of falling debris.
• Leave the building as quickly as possible. Do not stop to retrieve personal possessions
or make phone calls.
• Do not use elevators.
Once you are out:
• Do not stand in front of windows, glass doors, or other potentially hazardous
areas.
• Move away from sidewalks or streets to be used by emergency offi cials or others
still exiting the building.
If you are trapped in debris:
• If possible, use a fl ashlight to signal your location to rescuers.
• Avoid unnecessary movement so you don’t kick up dust.
• Cover your nose and mouth with anything you have on hand. (Dense-weave
cotton material can act as a good fi lter. Try to breathe through the material.)
• Tap on a pipe or wall so rescuers can hear where you are.
• If possible, use a whistle to signal rescuers.
• Shout only as a last resort. Shouting can cause a person to inhale dangerous
amounts of dust.

Biological
Threats
4.3 Biological Threats Are You Ready?
156
Biological agents are organisms or toxins that can kill or incapacitate people, livestock,
and crops. The three basic groups of biological agents that would likely be
used as weapons are bacteria, viruses, and toxins. Most biological agents are diffi
cult to grow and maintain. Many break down quickly when exposed to sunlight
and other environmental factors, while others, such as anthrax spores, are very
long lived. Biological agents can be dispersed by spraying them into the air, by
infecting animals that carry the disease to humans, and by contaminating food and
water. Delivery methods include:
• Aerosols—biological agents are dispersed into the air, forming a fi ne mist
that may drift for miles. Inhaling the agent may cause disease in people or
animals.
• Animals—some diseases are spread by insects and animals, such as fl eas,
mice, fl ies, mosquitoes, and livestock.
• Food and water contamination—some pathogenic organisms and toxins
may persist in food and water supplies. Most microbes can be killed, and toxins
deactivated, by cooking food and boiling water. Most microbes are killed
by boiling water for one minute, but some require longer. Follow offi cial
instructions.
• Person-to-person—spread of a few infectious agents is also possible. Humans
have been the source of infection for smallpox, plague, and the Lassa
viruses.
Specifi c information on biological agents is available at the Centers for Disease
Control and Prevention’s Web site, www.bt.cdc.gov.
Take Protective Measures
Before a Biological Attack The following are guidelines for what you should do to prepare for a biological
threat:
• Check with your doctor to ensure all required or suggested immunizations are
up to date. Children and older adults are particularly vulnerable to biological
agents.
Are You Ready? Biological Threats 4.3

• Consider installing a High Effi ciency Particulate Air (HEPA) fi lter in your furnace
return duct. These fi lters remove particles in the 0.3 to 10 micron range
and will fi lter out most biological agents that may enter your house. If you
do not have a central heating or cooling system, a stand-alone portable HEPA
fi lter can be used.
In the event of a biological attack, public health offi cials may not immediately be During a Biological Attack
able to provide information on what you should do. It will take time to determine
what the illness is, how it should be treated, and who is in danger. Watch
television, listen to radio, or check the Internet for offi cial news and information
including signs and symptoms of the disease, areas in danger, if medications or
vaccinations are being distributed, and where you should seek medical attention if
you become ill.
The fi rst evidence of an attack may be when you notice symptoms of the disease
caused by exposure to an agent. Be suspicious of any symptoms you notice, but
do not assume that any illness is a result of the attack. Use common sense and
practice good hygiene.
If you become aware of an unusual and suspicious substance nearby:
• Move away quickly.
• Wash with soap and water.
• Contact authorities.
• Listen to the media for offi cial instructions.
• Seek medical attention if you become sick.
If you are exposed to a biological agent:
• Remove and bag your clothes and personal items. Follow offi cial instructions
for disposal of contaminated items.
• Wash yourself with soap and water and put on clean clothes.
• Seek medical assistance. You may be advised to stay away from others or even
quarantined.
Filtration in Buildings
Building owners and managers should determine the type and level of
fi ltration in their structures and the level of protection it provides against
biological agents. The National Institute of Occupational Safety and
Health (NIOSH) provides technical guidance on this topic in their publication
Guidance for Filtration and Air-Cleaning Systems to Protect Building Environments
from Airborne Chemical, Biological, or Radiological Attacks. To obtain a copy, call

After a Biological Attack In some situations, such as the case of the anthrax letters sent in 2001, people may
be alerted to potential exposure. If this is the case, pay close attention to all offi cial
warnings and instructions on how to proceed. The delivery of medical services
for a biological event may be handled differently to respond to increased demand.
The basic public health procedures and medical protocols for handling exposure to
biological agents are the same as for any infectious disease. It is important for you
to pay attention to offi cial instructions via radio, television, and emergency alert
systems.
Using HEPA Filters
HEPA fi lters are useful in biological attacks. If you have a central heating
and cooling system in your home with a HEPA fi lter, leave it on if it
is running or turn the fan on if it is not running. Moving the air in the
house through the fi lter will help remove the agents from the air. If you
have a portable HEPA fi lter, take it with you to the internal room where
you are seeking shelter and turn it on.
If you are in an apartment or offi ce building that has a modern, central
heating and cooling system, the system’s fi ltration should provide a relatively
safe level of protection from outside biological contaminants.
HEPA fi lters will not fi lter chemical agents.

4.4 Chemical Threats Are You Ready?
160
Chemical agents are poisonous vapors, aerosols, liquids, and solids that have toxic
effects on people, animals, or plants. They can be released by bombs or sprayed
from aircraft, boats, and vehicles. They can be used as a liquid to create a hazard to
people and the environment. Some chemical agents may be odorless and tasteless.
They can have an immediate effect (a few seconds to a few minutes) or a delayed
effect (2 to 48 hours). While potentially lethal, chemical agents are diffi cult to deliver
in lethal concentrations. Outdoors, the agents often dissipate rapidly. Chemical
agents also are diffi cult to produce.
A chemical attack could come without warning. Signs of a chemical release include
people having diffi culty breathing; experiencing eye irritation; losing coordination;
becoming nauseated; or having a burning sensation in the nose, throat, and lungs.
Also, the presence of many dead insects or birds may indicate a chemical agent
release.
Take Protective Measures
Before a Chemical Attack The following are guidelines for what you should do to prepare for a chemical
threat:
• Check your disaster supplies kit to make sure it includes:
- A roll of duct tape and scissors.
- Plastic for doors, windows, and vents for the room in which you will shelter
in place. To save critical time during an emergency, pre-measure and cut the
plastic sheeting for each opening.
• Choose an internal room to shelter, preferably one without windows and on
the highest level.
During a Chemical Attack The following are guidelines for what you should do in a chemical attack.
If you are instructed to remain in your home or offi ce building, you should:
• Close doors and windows and turn off all ventilation, including furnaces, air

• Seek shelter in an internal room and take your disaster supplies kit.
• Seal the room with duct tape and plastic sheeting.

authorities announce it is safe to do so.
A person affected by a chemical agent requires immediate medical attention from a
professional. If medical help is not immediately available, decontaminate yourself
and assist in decontaminating others.
Decontamination guidelines are as follows:
• Use extreme caution when helping others who have been exposed to chemical
agents.
• Remove all clothing and other items in contact with the body. Contaminated
clothing normally removed over the head should be cut off to avoid contact
with the eyes, nose, and mouth. Put contaminated clothing and items into a
plastic bag and seal it. Decontaminate hands using soap and water. Remove
eyeglasses or contact lenses. Put glasses in a pan of household bleach to decontaminate
them, and then rinse and dry.
• Flush eyes with water.
• Gently wash face and hair with soap and water before thoroughly rinsing
with water.
• Decontaminate other body areas likely to have been contaminated. Blot (do
not swab or scrape) with a cloth soaked in soapy water and rinse with clear
water.
• Change into uncontaminated clothes. Clothing stored in drawers or closets is
likely to be uncontaminated.
• Proceed to a medical facility for screening and professional treatment.

Nuclear
Blast
4.5 Nuclear Blast Are You Ready?
164
A nuclear blast is an explosion with intense light and heat, a damaging pressure
wave, and widespread radioactive material that can contaminate the air, water, and
ground surfaces for miles around. A nuclear device can range from a weapon carried
by an intercontinental missile launched by a hostile nation or terrorist organization,
to a small portable nuclear devise transported by an individual. All nuclear
devices cause deadly effects when exploded, including blinding light, intense heat
(thermal radiation), initial nuclear radiation, blast, fi res started by the heat pulse,
and secondary fi res caused by the destruction.
Hazards of Nuclear Devices
The extent, nature, and arrival time of these hazards are diffi cult to predict. The
geographical dispersion of hazard effects will be defi ned by the following:
• Size of the device. A more powerful bomb will produce more distant effects.
• Height above the ground the device was detonated. This will determine the
extent of blast effects.
• Nature of the surface beneath the explosion. Some materials are more likely
to become radioactive and airborne than others. Flat areas are more susceptible
to blast effects.
• Existing meteorological conditions. Wind speed and direction will affect arrival
time of fallout; precipitation may wash fallout from the atmosphere.
Radioactive Fallout
Even if individuals are not close enough to the nuclear blast to be affected by
the direct impacts, they may be affected by radioactive fallout. Any nuclear blast
results in some fallout. Blasts that occur near the earth’s surface create much
greater amounts of fallout than blasts that occur at higher altitudes. This is because
the tremendous heat produced from a nuclear blast causes an up-draft of
air that forms the familiar mushroom cloud. When a blast occurs near the earth’s
surface, millions of vaporized dirt particles also are drawn into the cloud. As
the heat diminishes, radioactive materials that have vaporized condense on the
particles and fall back to Earth. The phenomenon is called radioactive fallout.
This fallout material decays over a long period of time, and is the main source of
residual nuclear radiation.
Fallout from a nuclear explosion may be carried by wind currents for hundreds
of miles if the right conditions exist. Effects from even a small portable device
exploded at ground level can be potentially deadly.
Nuclear radiation cannot be seen, smelled, or otherwise detected by normal
senses. Radiation can only be detected by radiation monitoring devices. This
makes radiological emergencies different from other types of emergencies, such
as fl oods or hurricanes. Monitoring can project the fallout arrival times, which
will be announced through offi cial warning channels. However, any increase in
surface build-up of gritty dust and dirt should be a warning for taking protective
measures.

Terrorism
Electromagnetic Pulse
In addition to other effects, a nuclear weapon detonated in or above the earth’s
atmosphere can create an electromagnetic pulse (EMP), a high-density electrical
fi eld. An EMP acts like a stroke of lightning but is stronger, faster, and shorter.
An EMP can seriously damage electronic devices connected to power sources or
antennas. This includes communication systems, computers, electrical appliances,
and automobile or aircraft ignition systems. The damage could range
from a minor interruption to actual burnout of components. Most electronic
equipment within 1,000 miles of a high-altitude nuclear detonation could be
affected. Battery-powered radios with short antennas generally would not be
affected. Although an EMP is unlikely to harm most people, it could harm those
with pacemakers or other implanted electronic devices.
Protection from a Nuclear Blast
The danger of a massive strategic nuclear attack on the United States is predicted
by experts to be less likely today. However, terrorism, by nature, is unpredictable.
If there were threat of an attack, people living near potential targets could be
advised to evacuate or they could decide on their own to evacuate to an area not
considered a likely target. Protection from radioactive fallout would require taking
shelter in an underground area or in the middle of a large building.
In general, potential targets include:
• Strategic missile sites and military bases.
• Centers of government such as Washington, DC, and state capitals.
• Important transportation and communication centers.
• Manufacturing, industrial, technology, and fi nancial centers.
• Petroleum refi neries, electrical power plants, and chemical plants.
• Major ports and airfi elds.
4.5 Nuclear Blast Are You Ready?
166
The three factors for protecting oneself from radiation and fallout are distance,
shielding, and time.
• Distance — the more distance between you and the fallout particles, the better.
An underground area such as a home or offi ce building basement offers
more protection than the fi rst fl oor of a building. A fl oor near the middle of
a high-rise may be better, depending on what is nearby at that level on which
signifi cant fallout particles would collect. Flat roofs collect fallout particles so
the top fl oor is not a good choice, nor is a fl oor adjacent to a neighboring fl at
roof.
• Shielding — the heavier and denser the materials—thick walls, concrete,
bricks, books and earth—between you and the fallout particles, the better.
• Time — fallout radiation loses its intensity fairly rapidly. In time, you will be
able to leave the fallout shelter. Radioactive fallout poses the greatest threat to
people during the fi rst two weeks, by which time it has declined to about 1
percent of its initial radiation level.
Remember that any protection, however temporary, is better than none at all, and
the more shielding, distance, and time you can take advantage of, the better.
Take Protective Measures
Before a Nuclear Blast To prepare for a nuclear blast, you should do the following:
• Find out from offi cials if any public buildings in your community have been
designated as fallout shelters. If none have been designated, make your own
list of potential shelters near your home, workplace, and school. These places
would include basements or the windowless center area of middle fl oors in
high-rise buildings, as well as subways and tunnels.
• If you live in an apartment building or high-rise, talk to the manager about
the safest place in the building for sheltering and about providing for building
occupants until it is safe to go out.
• During periods of increased threat increase your disaster supplies to be adequate
for up to two weeks.

If an attack warning is issued:
• Take cover as quickly as you can, below ground if possible, and stay there
until instructed to do otherwise.
• Listen for offi cial information and follow instructions.
If you are caught outside and unable to get inside immediately:
• Do not look at the fl ash or fi reball—it can blind you.
• Take cover behind anything that might offer protection.
• Lie fl at on the ground and cover your head. If the explosion is some distance
away, it could take 30 seconds or more for the blast wave to hit.
• Take shelter as soon as you can, even if you are many miles from ground zero
where the attack occurred—radioactive fallout can be carried by the winds for
hundreds of miles. Remember the three protective factors: Distance, shielding,
and time.
Decay rates of the radioactive fallout are the same for any size nuclear device. After a Nuclear Blast
However, the amount of fallout will vary based on the size of the device and its
proximity to the ground. Therefore, it might be necessary for those in the areas
with highest radiation levels to shelter for up to a month.
The heaviest fallout would be limited to the area at or downwind from the explosion,
and 80 percent of the fallout would occur during the fi rst 24 hours.
People in most of the areas that would be affected could be allowed to come out of
shelter within a few days and, if necessary, evacuate to unaffected areas.
Taking shelter during a nuclear blast is absolutely necessary. There
are two kinds of shelters—blast and fallout. The following describes
the two kinds of shelters:
• Blast shelters are specifi cally constructed to offer some protection
against blast pressure, initial radiation, heat, and fi re. But
even a blast shelter cannot withstand a direct hit from a nuclear
explosion.
• Fallout shelters do not need to be specially constructed for
protecting against fallout. They can be any protected space,
provided that the walls and roof are thick and dense enough to
absorb the radiation given off by fallout particles.

Radiological Dispersion
Device (RDD)
4.6 Radiological Dispersion Devices (RDD) Are You Ready?
170
Terrorist use of an RDD—often called “dirty nuke” or “dirty bomb”—is considered
far more likely than use of a nuclear explosive device. An RDD combines a
conventional explosive device—such as a bomb—with radioactive material. It is
designed to scatter dangerous and sub-lethal amounts of radioactive material over a
general area. Such RDDs appeal to terrorists because they require limited technical
knowledge to build and deploy compared to a nuclear device. Also, the radioactive
materials in RDDs are widely used in medicine, agriculture, industry, and research,
and are easier to obtain than weapons grade uranium or plutonium.
The primary purpose of terrorist use of an RDD is to cause psychological fear and
economic disruption. Some devices could cause fatalities from exposure to radioactive
materials. Depending on the speed at which the area of the RDD detonation
was evacuated or how successful people were at sheltering-in-place, the number
of deaths and injuries from an RDD might not be substantially greater than from a
conventional bomb explosion.
The size of the affected area and the level of destruction caused by an RDD would
depend on the sophistication and size of the conventional bomb, the type of radioactive
material used, the quality and quantity of the radioactive material, and
the local meteorological conditions—primarily wind and precipitation. The area
affected could be placed off-limits to the public for several months during cleanup
efforts.
Take Protective Measures
Before an RDD Event There is no way of knowing how much warning time there will be before an attack
by terrorists using an RDD, so being prepared in advance and knowing what
to do and when is important. Take the same protective measures you would for
fallout resulting from a nuclear blast.
During an RDD Event While the explosive blast will be immediately obvious, the presence of radiation
will not be known until trained personnel with specialized equipment are on the
scene. Whether you are indoors or outdoors, home or at work, be extra cautious.
It would be safer to assume radiological contamination has occurred—particularly
in an urban setting or near other likely terrorist targets—and take the proper precautions.
As with any radiation, you want to avoid or limit exposure. This is particularly
true of inhaling radioactive dust that results from the explosion. As you seek
shelter from any location (indoors or outdoors) and there is visual dust or other
contaminants in the air, breathe though the cloth of your shirt or coat to limit your
exposure. If you manage to avoid breathing radioactive dust, your proximity to the
radioactive particles may still result in some radiation exposure.

and dense shielding as possible
between you and the outdoors where
the radioactive material may be.
• Seal windows and external doors
that do not fi t snugly with duct tape
to reduce infi ltration of radioactive
particles. Plastic sheeting will not
provide shielding from radioactivity
nor from blast effects of a nearby
explosion.
• Listen for offi cial instructions and

After fi nding safe shelter, those who may have been exposed to radioactive material After an RDD Event
should decontaminate themselves. To do this, remove and bag your clothing (and
isolate the bag away from you and others), and shower thoroughly with soap and
water. Seek medical attention after offi cials indicate it is safe to leave shelter.
Contamination from an RDD event could affect a wide area, depending on the
amount of conventional explosives used, the quantity and type of radioactive material
released, and meteorological conditions. Thus, radiation dissipation rates vary,
but radiation from an RDD will likely take longer to dissipate due to a potentially
larger localized concentration of radioactive material.
Follow these additional guidelines after an RDD event:
• Continue listening to your radio or watch the television for instructions from
local offi cials, whether you have evacuated or sheltered-in-place.
• Do not return to or visit an RDD incident location for any reason.
• Follow the instructions for recovering from a disaster in Part 5.

The Homeland Security Advisory System was designed to provide a national framework
and comprehensive means to disseminate information regarding the risk of
terrorist acts to the following:
• Federal, state, and local authorities
• The private sector
• The American people
This system provides warnings in the form of a set of graduated “threat conditions”
that increase as the risk of the threat increases. Risk includes both the probability
of an attack occurring and its potential gravity. Threat conditions may be
assigned for the entire nation, or they may be set for a particular geographic area
or industrial sector. At each threat condition, government entities and the private
sector, including businesses and schools, would implement a corresponding set of
“protective measures” to further reduce vulnerability or increase response capability
during a period of heightened alert.
There are fi ve threat conditions, each identifi ed by a description and corresponding
color. Assigned threat conditions will be reviewed at regular intervals to determine
whether adjustments are warranted.
Threat Conditions and Associated
Protective Measures
There is always a risk of a terrorist threat. Each threat condition assigns a level
of alert appropriate to the increasing risk of terrorist attacks. Beneath each threat
condition are some suggested protective measures that the government, the private
sector, and the public can take.
In each case, as threat conditions escalate, protective measures are added to those
already taken in lower threat conditions. The measures are cumulative.

الله يسعدك ماقصرتي بس انا قصدي يكون مفهوم اكثر يعني تعريفه واثاره على المجتمع وموقف الاسلام منه تكفوووون ساعدوني اكثر الف شكر لك اختي

Terrorism
is the systematic use of terror especially as a means of coercion.At present, there is no internationally agreed definition of terrorism. Common definitions of terrorism refer only to those violent acts which are intended to create fear (terror), are perpetrated for an ideological goal (as opposed to a lone attack), and deliberately target or disregard the safety of non-combatants (civilians).
Some definitions also include acts of unlawful violence and war. The history of terrorist organizations suggests that they do not select terrorism for its political effectiveness.Individual terrorists tend to be motivated more by a desire for social solidarity with other members of their organization than by political platforms or strategic objectives, which are often murky and undefined.
The word "terrorism" is politically and emotionally charged, and this greatly compounds the difficulty of providing a precise definition. Studies have found over 100 definitions of “terrorism."The concept of terrorism may itself be controversial as it is often used by state authorities to delegitimize political or other opponents, and potentially legitimize the state's own use of armed force against opponents (such use of force may itself be described as "terror" by opponents of the state). A less politically and emotionally charged, and more easily definable, term is violent non-state actor (though the semantic scope of this term includes not only "terrorists," while excluding some individuals or groups who have previously been described as "terrorists").
Terrorism has been practiced by a broad array of political organizations for furthering their objectives. It has been practiced by both right-wing and left-wing political parties, nationalistic groups, religious groups, revolutionaries, and ruling governmentsOne form is the use of violence against noncombatants for the purpose of gaining publicity for a group, cause, or individual.

Therefore, we must understand the title, and its impact on Muslims, and that Italpson Basmt Islam, and who are in such an action are far away from the approach of the Holy Prophet peace be upon him, who was hurt in himself and his family and his companions was his will to strengthen the link with patience and God the Lord of the Worlds , did not tell them then cold aggression against infidels of Quraish, or acts of violence, murder, looting, or otherwise, it was the only way is to have patience and forgiveness, and stop even on what happens to them in the religion of God. What about modern folks do not have teeth guided by knowledge, or experience in the pitfalls of life to protect them from danger, drifting behind the symbols and the need to spread fear and panic and destruction in the lands of Islam, that this category need to review the matter and determine its trajectory, and to return to the scientists of the nation's workers.

The impact of terrorism:
Each plant harvest and planting good poem out with the permission of his Lord, and that slag does not go out except Nkda, and ere Bmharit recklessness, and sows discord, and tell of violence, will perish and forks a lump in his throat, and will burn up the brunt of.

The effects of terrorism, which sees the near and long term as follows:
(1) to take lives. (2) loss of selves. (3) destruction of property. (4) to spread fear and terror. (5) planting hatred, hatred. (6) mineralization is good. (7) to weaken the nation and dispel the gains. (8) shed the enemies of God and enable them to Nation of Islam.
