"The Turkish government has closed its airspace to military aircraft and as a result air operations at Incirlik Air Base have been halted at this time," the Pentagon Press Secretary Peter cook said.
"US officials are working with the Turks to resume air operations there as soon as possible," he said.
The US is using the Incirlik air base in Turkey to fly missions against the extremists in Syria and Iraq.
US facilities at Incirlik are operating on internal power sources and a loss of commercial power to the base has not affected base operations, he noted.
Meanwhile, the Pentagon is continuing with its efforts to fully account for all Department of Defense personnel in Turkey.
"All indications at this time are that everyone is safe and secure. We will continue to take the necessary steps to ensure the safety and security of our service members, our civilians, their families and our facilities," Cook said.
