“In one brazen attack on September 8, 2006, a suicide bomber hit a U.S. convoy just outside the American embassy in Kabul [Afghanistan], killing sixteen Afghans and two U.S. guards. The resulting crackdown led to the arrests of a suicide bomber network in the city, which revealed to interrogators how extremist groups in Pakistan supplied the group with explosives. Several captured Afghan and Pakistani suicide bombers recounted how they were recruited in Pakistani madrassas, then moved to safe houses in Quetta and Chaman [Pakistan], where they were trained. Taliban couriers then took them into Afghanistan, where they were lodged at safe houses and provided with explosives and cars.”
