Doğu Çalışma Grubu

The Doğu Çalışma Grubu (DÇG; East Study Group or East Working Group) was an alleged group within the Turkish military said to be linked to the Ergenekon organization, and possibly organised within the Turkish Gendarmerie's JITEM. According to former PKK commander Şemdin Sakık, the group was formed in 1993 and carried out a number of assassinations in preparation for the 1993 alleged Turkish military coup.

According to Sakık, these assassinations included (in 1993) President Turgut Özal, former Major Cem Ersever, former Turkish Gendarmerie general commander Eşref Bitlis and General Bahtiyar Aydın. Turgut Özal died in office on 17 April 1993 in suspicious circumstances, and a month later the May 24, 1993 PKK ambush took place, breaking the peace process which Özal had led. Sakık maintains the attack was part of the DÇG's coup plans.

Sakık also ascribes the death of Colonel Rıdvan Özden (1995) to the DÇG.
