A nationwide ground stop has been issued for all US airports due to a communication issue impacting every air route traffic control center in the country, U.S. Transportation Secretary Sean Duffy said on Friday, Nov. 13.

Nearly 7,000 flights have been delayed or cancelled so far, data shows.

The Federal Aviation Administration (FAA) notice said the ground stop was imposed “due to extraordinary circumstances and for reasons of safety,” and that inbound international flights “will be managed on a case by case basis.”

Duffy said immediate updates will be provided as they come in.

This is a developing story.
