A US F-22 fighter jet has shot down an "unidentified object" flying over northern Canada.
"I ordered the take down of an unidentified object that violated Canadian airspace," Trudeau said, adding that both Canadian and US aircraft were scrambled, and a US F-22 successfully took down the object.
Trudeau said the object was shot down over the Yukon, a Canadian territory, adding that Canadian forces will recover and analyze the object's wreckage.
On Friday, the US shot down another unidentified object flying roughly 40,000 feet over Alaska, and one week ago, the US took down a Chinese surveillance balloon off the coast of South Carolina.
US officials have said the Chinese balloon was part of an operation to gather intelligence on global militaries, and was studying "strategic bases" in the US.
