Find out more about the deadliest terrorists, including Osama bin Laden, Jamal Ahmad Mohammad Al Badawi, Abu Ibrahim, Fahd al-Quso and Jainal Antel Sali.

For the average American, the very mention of the word “terrorism” would bring back painful memories of the September 11 attacks in which almost 3,000 people were killed. The attacks, executed by the militant group Al-Qaeda, were planned by the group’s leader Osama bin Laden. Besides these attacks, bin Laden was also behind other mass-casualty attacks worldwide. He was finally killed in 2011 in a covert operation undertaken under President Obama. While bin Laden has been killed, America’s war against terrorism continues as there are still numerous terrorists named in the list of FBI Most Wanted Terrorists. One of these notorious men, Jamal Ahmad Mohammad Al Badawi, is convicted of having a role in the USS Cole bombing. He is still at large and there is a reward of $5 million for information leading to his capture. Another terrorist on the list is Abu Ibrahim, wanted in connection with the 1982 bombing of Pan Am Flight 830. While the government is still seeking information regarding several absconding terrorists, many other terrorists who were once on the list have already been captured or killed. Fahd al-Quso, Jainal Antel Sali, and Khadafi Abubakar Janjalani are among the ones who have been killed. Check out this section to know more about some of the deadliest terrorists world has ever seen.
