The US has shot down an unknown object flying in its airspace, off the coastline of Alaska – just days after it downed a Chinese “spy” balloon.
The object, shot down on the order of President Joe Biden, was flying at a high-altitude of about 40,000 feet and was the size of a small car, the White House said.
It posed a “reasonable threat” to the safety of civilian flights, said John Kirby, the White House National Security Council spokesman.
It was unclear where the object came from.
“We don’t know who owns this object,” said Mr Kirby.
US officials said: “Out of an abundance of caution and at the recommendation of the Pentagon, President Biden ordered the military to down the object over water”.
An F-22 Aircraft took down the object using a Sidewinder missile over territorial waters – now frozen.
There was no indication the object was manned, nor did the Pentagon know what speed it was travelling at.
The incident happened just days after the US downed a Chinese balloon believed to be a spy aircraft.
China maintained the balloon was an airship for scientific research that had accidentally flown over the US.
That balloon was shot down by fighter jets off the coast of South Carolina – with the US military starting to collect the debris shortly thereafter.
What are spy balloons?
Biden’s response was measured but anchored in reality
The incident sparked a diplomatic row between China and the US, with Secretary of State Antony Blinken postponing a visit to China that had been due to start just a few days later.
The “spy” balloon was believed to have flown over the Aleutian Islands, off the coast of Alaska, and through Canada before entering the US.
Military and defence leaders had considered shooting the balloon out of the sky but decided against it due to the safety risk from falling debris.
