Today's edition of the Sozcu newspaper carried empty columns with writers' names and also left the weather section blank.
It was a response to yesterday's detentions of Mediha Olgun, the editor of Sozcu's website, and reporter Gokmen Ulu. Detention warrants were also issued for owner Burak Akbay and head of finance Yonca Kaleli.
They are accused of committing crimes on behalf of the network of US-based cleric Fethullah Gulen. The Turkish government blames Gulen for last summer's failed coup attempt, an allegation Gulen denies.
