Turkey's mass-circulation daily Sozcu printed an entirely blank edition on Saturday after two of its journalists were detained in police raids.
The "press freedom special edition" of the newspaper was 20 pages and available at newsstands. 
The two journalists in detention are accused of having links to Fethullah Gulen, a US-based cleric the government blames for last year's abortive coup. 
Sozcu is a staunchly secular and left-leaning daily, the third largest by circulation in Turkey. It is often critical of the government of President Recep Tayyip Erdogan and has often been opposed to the Gulenists movement. 
The detentions took place on May 19, which is a public holiday in Turkey honouring the republic's founder, Mustafa Kemal Ataturk. 
The journalists are Internet editor Mediha Olgun and Izmir correspondent Gokmen Ulu, the private Dogan news agency said, the latter having reported on Erdogan's holiday plans last year around the time of the failed coup.
Cumhuriyet newspaper, another left-leaning outlet, has also been targeted by the government over the past two years. More than a dozen Cumhuriyet staff are in jail. 
At least 145 media workers are behind bars in Turkey, which ranks 155 out of 180 countries on the Reporters Without Borders (RSF) Press Freedom Index. Dozens of media outlets have been shuttered in the past year by decrees issued under the ongoing state of emergency.
Separately Reporters Without Borders is calling for the Turkish authorities to release French photographer Mathias Depardon who "has been detained arbitrarily for the past eleven days."
