Up until 2004, suicide bombings were almost unheard of in Afghanistan. But beginning that year, the Taliban launches six suicide attacks. In 2005, the number increases to 21. In 2006, the number skyrockets to 141, causing 1,166 casualties. In 2007, the number remains steady at 137, but the number of casualties increases 50 percent to 1,730. On September 8, 2006, a suicide bomber hits a US convoy just outside the US embassy in Kabul, killing two US soldiers and 16 Afghans. The resulting investigation uncovers a suicide bomb support network in Kabul that links to militants in the tribal regions of Pakistan. Amrullah Saleh, the head of Afghanistan’s intelligence agency, says: “Every single bomber we arrest is linked to Pakistan in some way. The training, provisions, explosives, technical equipment, are all being manufactured in Pakistan, and the CIA knows this.” [Rashid, 2008, pp. 366-367]
