The operation marks the third day in a row that an unidentified object was shot down over North American airspace. An unidentified object was shot down over northern Canada on Saturday. On Friday, an unidentified object was shot down in Alaska airspace by a US F-22.
White House National Security Council spokesman John Kirby said that the Department of Defense shot down a "high altitude object" that was in Alaska's airspace in the last 24 hours.
