“The four suicide bombers–three of them of Pakistani origin–who carried out the July 7, 2005, attacks on the London Underground that killed fifty-six people and injured seven hundred were connected to FATA [Pakistan’s Federally Administered Tribal Areas]. The ringleader, Mohammed Siddique Khan, visited FATA in 2003 and 2004, when he had ‘some contact with al Qaeda figures and some relevant training,’ according to a British government report.”
