According to the memos, the Taliban are guided in their attacks on Afghan and NATO forces from Pakistan, which is a safe haven for militants. They reveal that Arabs, Chechens, Pakistanis, and Muslims from European states sneak into Afghanistan from Pakistan to fight NATO and Afghan troops. Gul has also been accused of re-organizing Afghanistan's second-largest militant group, Hizb-i-Islami, led by Gulbuddin Hekmatyar, and the Haqqani Network, a Waziristan-based rebel outfit. Mr. Gul allegedly visited Waziristan in January 2008 to devise a plan to avenge the killing of Ahmad Alkani, an al-Qaeda leader killed in a U.S. drone missile strike.

He is also accused of directing Pakistani Taliban to wage a jihad in Afghanistan instead of Pakistan. The former spy chief is said to have handed over 65 vehicles full of ammunition to the Taliban. The agency he headed provided 7,000 Kalashnikov assault rifles to the fighters in Kunar, and 1,000 motorcycles to the Haqqani Network for suicide attacks in southeastern Afghanistan. The documents also link Gul to the abduction of United Nations workers on the Kabul-Nangarhar highway.
