FAA Grounds All Flights Between U.S. and Istanbul After Airport Bombing

The Federal Aviation Administration (FAA) has grounded all flights between the U.S. and Istanbul, Turkey following the suicide attacks at Istanbul’s Ataturk airport that left dozens dead.

A “ground stop” order has been put in place for any U.S. flights leaving for Istanbul and any U.S.-bound flights from the Turkish city, the agency confirmed in a statement to TIME.

The FAA declined to say how long the order may last for and how many flights are impacted.

Officials told the Associated Press that nearly 50 people were killed, though that number was later revised to at least 31 dead and 60 people wounded after at least three suicide bombers attacked the international terminal entrance, the Associated Press reports.
