The U.S. embassies in Nairobi, Kenya and Dar es Salaam, Tanzania were bombed in 1998. Over 200 people were killed in Nairobi and 10 in Dar es Salaam. Usama bin Laden and al-Qaeda claimed responsibility for the bombings, which were carried out through truck bombs. The U.S. responded with missile strikes in Afghanistan and Sudan. Improved security policies were implemented, including relocating the embassies to more secure locations away from busy areas.
