An American fighter plane is said to have shot down an object over American airspace in Alaska on Friday.

The order must have come from US President Joe Biden, the White House confirms according to Reuters.

It is unclear what kind of object it is, but it should be smaller than the attention-grabbing Chinese balloon that floated around the country's airspace earlier this week, reports Reuters.

The object should be as big as a small car, says the White House according to Reuters.
