The Camp Chapman attack was a suicide attack by Humam Khalil Abu-Mulal al-Balawi against the Central Intelligence Agency facility inside Forward Operating Base Chapman on December 30, 2009. One of the main tasks of the CIA personnel stationed at the base was to provide intelligence supporting drone attacks in Pakistan. Seven American CIA officers and contractors, an officer of Jordan's intelligence service, and an Afghan working for the CIA were killed when al-Balawi detonated a bomb sewn into a vest he was wearing. Six other American CIA officers were wounded. The bombing was the most lethal attack against the CIA in more than 25 years.
