WASHNGTON (AP) — Normal operations at airports in the Washington, D.C., area resumed about an hour after they were suspended Sunday evening because of a problem at a major air traffic control facility, the Federal Aviation Administration said.

The FAA said on Twitter that the operations at Reagan and Dulles international airports have restarted after repairs to a communications system were made at the Potomac Terminal Radar Approach Control facility.

While the repairs were underway, departures from National and Dulles international airports were subjected to a ground stop, the FAA said.
