According to a July 2001 report from Human Rights Watch, the ISI has been “bankrolling Taliban military operations… arranging training for its fighters, planning and directing offensives, providing and facilitating shipments of ammunition and fuel, and on several occasions apparently directly providing combat support.”
[Slate, 10/9/2001] The report further states that Pakistan’s assistance “include[s] soliciting funding for the Taliban, bankrolling Taliban operations, providing diplomatic support as the Taliban’s virtual emissaries abroad, arranging training for Taliban fighters, recruiting skilled and unskilled manpower to serve in Taliban armies… In April and May 2001 Human Rights Watch sources reported that as many as thirty trucks a day were crossing the Pakistan border; sources inside Afghanistan reported that some of these convoys were carrying artillery shells, tank rounds, and rocket-propelled grenades. Such deliveries are in direct violation of UN sanctions.… Pakistan’s army and intelligence services, principally the Inter-Services Intelligence Directorate (ISI), contribute to making the Taliban a highly effective military force. While these Pakistani agencies do not direct the policies of the [Taliban’s army], senior Pakistani military and intelligence officers help plan and execute major military operations. A retired senior Pakistani military officer claimed in an interview with Human Rights Watch that up to 30 percent of Taliban fighting strength is made up of Pakistanis serving in units organized by [Pakistani] political parties.”
