Turkey continues its crackdown on government opponents following a coup attempt in July.
Under a legislative decree published Saturday, Turkish authorities fired more than 10,000 public servants for alleged ties to the movement affiliated with exiled cleric Fethullah Gulen, and shut down 15 Kurdish media companies for alleged ties to militant Kurdish groups, state-run news agency Anadolu reported.
The new decree "made it easier to sack public officials believed to be members of terrorist organizations or groups involved in activities against the country's national security," Anadolu reported.
The 10,131 dismissed government employees were alleged to have ties to Gulen, a US-based Turkish cleric, and his movement, which Turkey blames for the failed July coup and considers a terrorist organization.
The decree also effectively grants President Recep Tayyip Erdogan the power to appoint all the heads of Turkey's universities by abolishing a system in which academics picked the top candidates for rectors of the schools. Academics had selected a slate of rector candidates at the institutions for more than two decades.
The 15 Kurdish media companies that were shut down are accused of ties to the Kurdistan Workers' Party, or PKK, which has been battling the Turkish state off and on for some 30 years.
Turkey, the United States and the European Union consider it to be a terrorist organization.
The media shutdown is the latest in an escalation of moves against prominent Kurds.
On Tuesday, authorities detained the two elected mayors of the predominantly Kurdish southeastern city of Diyarbakir, also over alleged PKK "terror links."
There have been calls in parts of Istanbul to protest the move to close the Kurdish media outlets and the detention of the mayors.
Rising tensions sparks US travel warning
The US Consulate in Istanbul ordered all civilian family members of its consulate staff to leave Turkey on Saturday.
The move follows a travel warning from the State Department.
"The Department of State made this decision based on security information indicating extremist groups are continuing aggressive efforts to attack US citizens in areas of Istanbul where they reside or frequent," the warning said.
A travel warning for southeast Turkey, especially urban centers near the Turkish-Syrian border, has been in effect since Monday.
