The FAA banned all flights into and out of Turkey for U.S. aircraft on Saturday, one day after a coup attempt rocked the country that is a NATO member and critical U.S. ally.

The agency issued a notice saying it was prohibiting all U.S. commercial and private aircraft from operating into or out of any airport in Turkey.

"The FAA is monitoring the situation in Turkey in coordination with our partners in the State Department and the Department of Homeland Security and will update the restrictions as the situation evolves," the FAA said in a statement.

U.S.air operations halted at Turkey air base

Turkey has been embroiled in turmoil since some segments of the military attempted to overthrow Turkish President Recep Tayyip Erdogan and the government Friday night. Military units closed key routes into Ankara and Istanbul and seized control of state-run television stations.

On Saturday, Erdogan said the coup had failed, and he vowed retribution against the plotters. "This government brought to power by the people is in charge. They won’t succeed as long as we stand against them by risking everything," he told a crowd in Istanbul.

The coup attempt has been a bloody one: Nearly 200 people have been killed in clashes and more than 2,000 military personnel have been detained. There were reports of continued fighting in some areas of the country.

Also Saturday, Turkey closed airspace to military aircraft around Incirlik Air Base, forcing the U.S. to stop air operations at the base. Incirlik is the base Turkey lets the U.S. use to launch missions against Islamic State forces.

Military coup in Turkey: What we know now

Turkey has been nearing a boiling point for months as a result of a government shake-up, a crackdown on dissidents and opposition media, renewed fighting in Kurdish areas and an uptick in criticism over Erdogan’s increasingly authoritarian rule.

The FAA halted flights to and from Istanbul's Ataturk Airport last month after a bombing at the airport. At least 41 people died and dozens more were injured June 28 when three Islamic State terrorists blew themselves up at the airport.
