Among other attacks are suicide bombings in 2007 in Algiers, a 2002 nightclub bombing in Bali, Indonesia, and the 1993 World Trade Center bombing.

Other attacks include the 2000 bombing of the U.S.S. cole and the 1998 bombing of the U.S. embassies in Nairobi, Kenya and Dar es Salaam in Tanzania. European attacks have included the bombing of commuter trains in Madrid, Spain and London, UK's transport system.
