If you must travel in an area where there has been a history of terrorist attacks or kidnappings make it a habit to:
Discuss with your family what they would do in the event of an emergency. Make sure your affairs are in order before leaving home.
As noted earlier, it’s a good idea to register your travel with the Department of State.
Remember to leave a detailed itinerary and the numbers or copies of your passport or other citizenship documents with a friend or relative in the United States.
Remain friendly but be cautious about discussing personal matters or your itinerary.
Leave no personal or business papers in your hotel room.
Watch for people following you or "loiterers" observing your comings and goings.
Keep a mental note of safe havens, such as police stations, hotels, and hospitals. Formulate a plan of action for what you will do if a bomb explodes or there is gunfire nearby.
Let someone else know what your travel plans are. Keep them informed if you change your plans.
Report any suspicious activity to local police, and to the nearest U.S. embassy or consulate.
Select your own taxicabs at random. Don't take a vehicle that is not clearly identified as a taxi. Compare the face of the driver with the one on his or her posted license.
If possible, travel with others.
Be sure of the identity of visitors before opening the door of your hotel room. Don't meet strangers at your hotel room, or at unknown or remote locations.
Refuse unexpected packages.
Check for loose wires or other suspicious activity around your car.
Be sure your vehicle is in good operating condition.
Drive with car windows closed in crowded streets. Bombs can be thrown through open windows.
If you are ever in a situation where somebody starts shooting, drop to the floor or get down as low as possible. Don't move until you are sure the danger has passed. Do not attempt to help rescuers and do not pick up a weapon. If possible, shield yourself behind a solid object. If you must move, crawl on your stomach.
