In June 2016 Önderoğlu was arrested after attending a meeting for Ozgur Gundem, a Kurdish newspaper, on World Press Freedom Day.[1] Journalist Ahmet Nesin and scholar Sebnem Korur Fincanci (head of the Turkish Human Rights foundation), who participated in the meeting with Önderoğlu, were also arrested,[8] and were accused of spreading "terrorism propaganda" in favor of the Kurdistan Workers' Party.[1][3] The three men had taken turns symbolically taking over the leadership of the newspaper to protest its harassment by the government.[3] The Turkish government of Recep Tayyip Erdogan accused the newspaper of spreading Kurdish "terrorism propaganda" and shut it down in August 2016. It is one of dozens of news organizations that have been forced to close by the government since the 2016 Turkish coup d'état attempt, while the Cumhuriyet, the country's oldest mainstream newspaper, had its offices raided and its editors arrested.[1][4] The number of newspapers shut down by the government has been estimated as 170.[5]
