A US fighter jet shot down an unidentified object over Canada on Saturday, the second such incident in North American skies since the dramatic downing of a suspected Chinese spy balloon a week ago.

Prime Minister Justin Trudeau said a joint US–Canadian military operation led to the takedown of the object, the latest in a series of mysterious air intrusions.

“Canadian and US aircraft were scrambled, and a US F-22 successfully fired at the object,” Trudeau tweeted Saturday.

Shortly after the 3:41 pm (2041 GMT) downing of the  object, aviation authorities shut down part of the airspace over the northwest US state of Montana after detecting what they called a “radar anomaly,” the US Northern Command said.

I ordered the take down of an unidentified object that violated Canadian airspace. @NORADCommand shot down the object over the Yukon. Canadian and U.S. aircraft were scrambled, and a U.S. F-22 successfully fired at the object.

In a sign of jitters over possible intrusions, Northern Command said US fighter jets took to the skies but “did not identify any object to correlate to the radar hits.” Skies were then reopened to commercial air traffic.

The object shot down in the Yukon was “small, cylindrical” in shape, said Canada’s defense minister, Anita Anand.

“The object was flying at an altitude of approximately 40,000 feet, had unlawfully entered Canadian airspace, and posed a reasonable threat to the safety of civilian flight,” Anand told reporters.

Trudeau said Canadian forces in the Yukon “will now recover and analyze the wreckage of the object.”

He said he spoke with US President Joe Biden over the latest incursion, while Anand also said she spoke with US Defense Secretary Lloyd Austin.

The new incursions into Alaska and the Yukon came after the United States said Wednesday that suspected Chinese spy balloons like the one it shot down February 4 were part of a “fleet” that has spanned five continents. NATO also voiced concern.

Anand, however, said “it would not be prudent for me to speculate on the origins of the object at this time.”

US and Canadian planes flew together to take on the object Saturday, the US Department of Defense and Anand said.

“President Biden authorized US fighter aircraft assigned to NORAD to work with Canada to take down a high-altitude airborne object over northern Canada today,” Pentagon Spokesman Pat Ryder said in a statement, referring to the North American Aerospace Defense Command.

An F-22 fighter jet fired an AIM 9X missile that brought it down, he said.
