All flights in the United States are grounded until further notice, “due to extraordinary circumstances and for reasons of safety,” the Federal Aviation Administration said in a statement.

The cause of the ground stop was not immediately clear, but an FAA spokesperson says there is a communications problem impacting Air Route Traffic Control Centers, which handle flights going across the country.

“Traffic should remain ground stopped until further notice,” the FAA said in an advisory. “International flights will be managed on a case by case basis.”
