It is widely agreed that after Hekmatyar failed to take over power in Afghanistan , the ISI helped to found the Afghan Taliban . The ISI and other parts of the Pakistan military subsequently provided financial , logistical , military and direct combat support to the Taliban until the September 11 attacks of 2001 . It is widely acknowledged that the ISI has given the Afghan Taliban safe havens inside Pakistan and supported the Taliban 's resurgence in Afghanistan after 9/11 helping them , especially the Haqqani network , carry out attacks inside Afghanistan . Pakistani officials deny this accusation . Allegations have been raised by international government officials , policy analysts and even Pakistani military officials that the ISI in conjunction with the military leadership has also provided some amount of support and refuge to al-Qaeda . Such allegations were increasingly issued when Al-Qaeda leader Osama Bin Laden was killed in 2011 while living in the Pakistani city of Abbottabad
