Gulbuddin Hikmatyar founded Hizb-I Islami Gulbuddin (HIG) as a faction of the Hizb-I Islami party in 1977, and it was one of the major mujahedin groups in the war against the Soviets. HIG has long-established ties with Bin Ladin. In the early 1990s, Hikmatyar ran several terrorist training camps in Afghanistan and was a pioneer in sending mercenary fighters to other Islamic conflicts. Hikmatyar offered to shelter Bin Ladin after the latter fled Sudan in 1996.
HIG has staged small attacks in its attempt to force US troops to withdraw from Afghanistan, overthrow the Afghan Transitional Administration (ATA), and establish a fundamentalist state.
HIG possibly could have hundreds of veteran fighters to call on.
