Afghan Civil War (1989–1992)
This group was the main opponent of the Hezb-e Islami group in the shared struggle against the Soviets and Najibullah. The two groups often fought against each other, even though they were both part of the same Islamist rebel movement against the communists. In one instance, Gulbuddin Hekmatyar attacked Massoud's troops and killed 36 of his commanders. In return, Massoud chased down four of Hekmatyar's men who were responsible for the attack and proceeded to hang them.
