The U.S. shot down a Chinese surveillance balloon off the Carolina coast on Saturday, after the high-altitude balloon spent the last week traveling across the country, according to several outlets.

An operation is reportedly underway to recover debris from the downed balloon, The Associated Press confirmed.

The Federal Aviation Administration (FAA) paused flights from three airports in North Carolina and South Carolina and closed additional airspace on Saturday afternoon in order to support the Defense Department in a “national security effort.” The balloon had been seen traveling over the Carolinas on Saturday.

The Hill has reached out to the Defense Department for comment.
