Turkey’s secularist Cumhuriyet daily Editor-in-Chief Murat Sabuncu and columnist Güray Öz were detained after police raided their residences on early Monday.

Police raied Sabuncu and Öz’s houses along with the house of daily’s CEO Akın Atalay and columnist Hikmet Çetinkaya on early monday upon the order of an İstanbul court which issued detention warrants against 13 people, including journalists, columnists and administratives from Cumhuriyet.

According to pro-government Sabah daily, an İstanbul court issued detention warrants for 13 journalists from Cumhuriyet daily over charges of helping terrorist Kurdistan Workers’ Party (PKK) and FETO.

FETO is a derogatory term and acronym of Fethullah Terrorist Organization, coined by President Tayyip Erdoğan and Justice and Development Party (AKP) government to refer to Gülen movement that Erdoğan and AKP accuses its inpirer US-based Turkish scholar of masterminding the failed coup attempt on July 15.

Hürriyet daily wrote that a detention warrant was also issued for Cumhuriyet daily CEO Atalay after it was revealed that he went abroad before police raided his house.

Police also searching houses of Cumhuriyet Foundation executives Turan Günay and Bülent Utku, Hürriyet reported.

The pro-government Yeni Şafak newspaper said on its website they were being investigated over alleged links to Gülen.

Cumhuriyet’s former Editor-in-Chief Can Dündar was sentenced to six years for publishing state secrets involving Ankara’s Syria operations. His conviction sparked censure from rights groups and Western governments worried about worsening human rights in Turkey under President Tayyip Erdoğan.

Police operations to Cumhuriyet editors, columnists and executives come after Turkey dismissed on Saturday a further 10,000 civil servants and closed 15 more media outlets over suspected links with militant groups and Gülen. More than 100,000 people had already been sacked or suspended and nearly 75,000 detained and 37,000 arrested since the failed coup attempt in an unprecedented crackdown that Erdoğan says is crucial to wipe out Gülen’s network from the state apparatus.
