Maplecroft puts Somalia at the top of its list, followed by Pakistan, Iraq, Afghanistan, and the Palestinian territories.
Somalia and its fragile U.N.-backed government is under threat from al-Shabab — Islamic extremists who control much of the country. They want to turn Somalia into a strict Islamic state.
The other top countries at an extreme risk for terrorism are Colombia, Thailand, the Philippines, Yemen, and Russia.
High risk countries include Iran, Nigeria, Spain, and Burma. The United States, Britain, and France are ranked as medium risk while Canada and Germany fall under the low risk category.
