A US F-22 fighter jet on Friday shot down an unidentified object flying high over Alaska, US officials said, less than a week after the military brought down a Chinese balloon that had flown across the United States.
A Sidewinder missile downed the latest craft, which was about the size of a small car, said US Brig Gen Patrick Ryder, the Pentagon's chief spokesperson.
"We don't know who owns this object," said White House spokesperson John Kirby, adding that it was unclear where it began its flight.
President Joe Biden ordered the shootdown, which was announced from the White House.
On February 4, another US F-22 fighter jet brought down what the US government called a Chinese surveillance balloon off the coast of South Carolina following its week-long journey across the United States and portions of Canada. China's government has said it was a civilian research vessel.
Some lawmakers criticized the president for not shooting down the Chinese balloon sooner. The US military had recommended waiting until it was over the ocean out of fear of injuries from falling debris.
The Pentagon and the White House declined to give a detailed description of the latest object, saying only that it was far smaller than the Chinese balloon.
US officials declined to speculate about what the object might be, even after a day of observation, raising questions about what kind of object could be so difficult to identify by experienced US pilots and intelligence officials.
The Pentagon said it was first detected on Thursday using ground radars. F-35 aircraft were then sent to investigate. The UFO was flying at about 40,000 feet (12,190 meters) in a northeasterly direction, posing a risk to civilian air traffic.
The object was shot down off the coast of northeastern Alaska over frozen US territorial waters near the Canadian border. Officials said it would be far easier to retrieve pieces of the object from the ice than it was with the Chinese balloon, pieces of which sank in the ocean when it was shot down.
