Dubai International Airport, one of the busiest in the world, was forced to briefly shut down departing flights on Friday because of what it said was “suspected drone activity,” the latest instance in which a major airport had to restrict air traffic over concerns about the remotely controlled devices.

The airport said in a statement that flight departures were suspended between 10:13 a.m. and 10:45 a.m. because of concerns about drone activity. Incoming flights were allowed to land, and the airport said on Twitter that operations were back to normal.

“Dubai Airports has worked closely with the appropriate authorities to ensure that the safety of airport operations is maintained at all times and to minimize any inconvenience to our customers,” the airport said.

The Dubai airport has grown rapidly in recent years, a reflection of changes in the region, and it has emerged as a busy hub for travelers heading all over the world.
