The 15 of August 1984 is an important date for the Turkish-Kurdish conflict as it marked the first PKK (Kurdistan Workers' Party) attack, led by Mahsum Korkmaz (known as "Agit") to say stop the slavery of the Kurdish people.

PKK forces attacked the gendarmerie station in Eruh in Siirt and killed one gendarmerie soldier and injured six soldiers and three civilians. Simultaneously PKK forces attacked a gendarmerie open air facility, officer housings and a gendarmerie station in Şemdinli, Hakkâri and killed two police officers and injured one police officer and a soldier.

The first attack was followed up by a raid on a police station in Siirt on August 17 which was soon followed by an attack that killed 3 of General Kenan Evren's Preidential Guards in Yüksekova and an ambush which killed 8 Turkish soldiers in Çukurca, in Hakkâri province.
