Eight people were detained during a police raid on a student apartment in Turkey’s Kayseri, Anadolu news agency reported Wednesday.

Detainees include university students as well as people wanted over their alleged ties to the Gulen movement, Anadolu said.

Turkey survived a military coup attempt on July 15, 2016 that killed 249 people. Following the putsch, the Justice and Development Party (AK Party) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen group, initiating a widespread purge aimed at cleansing members of the movement from within state institutions, dehumanizing its popular figures and putting them in custody.

More than 511,000 people were detained since the summer of 2016.
