The 2015 Aksu colliery attack took place on 18 September 2015, when a group of terrorists, suspected to be Uyghurs, attacked workers and security guards at a coal mine in Aksu City, Xinjiang, leaving at least 50 dead and 50 wounded. When local police arrived at the scene, the attackers rammed the police's vehicles before fleeing into the mountains. The majority of the victims of the attack were members of the Han ethnic group.
