Canada has shot down an 'unidentified object' after it entered its airspace, the country's prime minister has said.
It comes one day after the US president ordered a fighter jet to shoot down an unidentified "high-altitude object" off Alaska.
In a tweet, Justin Trudeau wrote: “I ordered the take down of an unidentified object that violated Canadian airspace. @NORADCommand shot down the object over the Yukon.
