The White House says that the U.S. military shot down an as yet unidentified flying object over northern Alaska on Thursday evening.

National Security Council spokesman John Kirby said that the object was “the size of a small car” and lacked an array of the kind carried by the Chinese spy balloon downed over the Atlantic last weekend. The object was at an altitude of 40,000 feet as it transited airspace over U.S. territorial waters near Prudhoe Bay. As with the balloon, the downing was performed by an F-22. The debris field is said to be small and located on solidly frozen ice. Beyond that, details are sparse.
