""The UN Security Council lifted sanctions against Hekmatyar, including a freeze that had been put on his assets, a comprehensive travel ban, and an arms embargo. Hekmatyar, the leader of the Islamist organization Hezb-i-Islami, had occasionally collaborated with al Qaeda and the Taliban after the 2001 US-led invasion of Afghanistan, despite disagreements between the various groups." "Gulbuddin Hekmatyar was nicknamed "The Butcher of Kabul" as he ordered thousands of killings during the civil war," "The agreement, which was the first of its kind since the Taliban launched their insurgency in 2001, was commended by numerous foreign governments, including the United States, as a step towards peace in the country.""
