Turkey has issued warrants for the detention of a further 47 journalists.
They are all former executives and senior journalists of the Zaman newspaper, allegedly associated with a US-based Muslim cleric accused over the failed coup, according to the state-run news agency.
The Anadolu agency said at least one journalist, former Zaman columnist Sahin Alpay, was detained on Wednesday.
Zaman, which was linked to the religious movement led by cleric Fethullah Gulen (pictured), was raided by police and seized by the government in March.
Earlier this week, warrants were issued against 42 other journalists, of whom 16 have been detained for questioning.
The detention of journalists and widescale purges of officials have raised concerns about a possible witch hunt after the violent coup attempt on 15 July that killed about 290 people.
President Tayyip Erdogan has detained 13,000 people since the failed plot to overthrow him.
