ISTANBUL — One journalist, who was on vacation, had his home raided in the early morning by the police. Others were called in to their bosses’ offices last week and fired, with little explanation. Dozens of reporters have had their press credentials revoked.

A pro-government newspaper, meanwhile, published a list of names and photographs of journalists suspected of treachery.

The witch-hunt environment that has enveloped Turkey in the wake of a failed military coup extended to the news media on Monday, as the government issued warrants for the detention of dozens of journalists.

The step followed the dismissals of tens of thousands of workers — teachers, bankers, police officers, soldiers, bureaucrats and others — as well as the arrests of thousands accused of ties to the conspiracy.
