Turkey has announced it can detain those suspected of being part of last week's failed coup for 30 days without trial.
An official statement also ordered the closure of over 1,000 private schools and more than 1,200 charities.
It comes after Turkey's president announced a three-month state of emergency on Wednesday.
In a televised speech, Recep Tayyip Erdogan warned there "may be more plans" from dissidents to try and overthrow the government.
The president said the decision was reached in order to "take the most efficient steps in order to remove this threat as soon as possible, which is a threat to democracy, to the rule of law, and to the rights and freedoms of citizens in our country".
At least 265 people are believed to have died in the violence last weekend.
More than 10,000 suspects - including top military generals - have been arrested since the attempted takeover.
Turkey has also banned academics from travelling abroad and suspended hundreds of officers from the Ankara police force.
