The New York-based Human Rights Watch warned this week that the detention or suspension of thousands of bureaucrats, judges, journalists and others is "an unvarnished move for an arbitrary, mass and permanent purge of the civil service."
On the detention of scores of journalists, Amnesty International's deputy director for Europe, Gauri van Gulik, said Turkey's government "is failing to make a distinction between criminal acts and legitimate criticism."
"Rather than stifling press freedom and intimidating journalists into silence, it is vital that Turkish authorities allow the media to do their work," she said, "and end this draconian clampdown on freedom of expression."
The decree Thursday targeted three news agencies, 16 television channels, 23 radio stations and 45 newspapers. It also discharged more than 2,400 military personnel for "complicity in the attempted coup," a senior Turkish official said.
The dismissed personnel included 1,200 commissioned officers from the navy, air and land forces. The Turkish armed forces said that 8,651 personnel - or 1.5 percent of the military - participated in the abortive coup and that the rebel faction used 35 planes, 37 helicopters, 74 tanks and three ships during the operation.
The assault took place over about 12 hours between the night of July 15 and morning of July 16, when the rogue soldiers surrendered to citizens and police who had fought back against the coup. Pro-coup pilots had used combat aircraft to bomb Turkey's parliament and presidential palace. The country's top leaders, however, emerged unscathed.
Since then, authorities have embarked on a massive campaign to detain, arrest and suspend tens of thousands of government employees for alleged links to the plot. Turkey's opposition parties have condemned the coup but are also warning against further repression.
"Those who are innocent should not be thrown into the fire with those who are guilty," Kemal Kilicdaroglu, the head of the leftist Republican People's Party (CHP), told the Associated Press on Wednesday.
