Four Russian aircraft were allegedly detected and intercepted on Monday by North American Aerospace Defense Command (NORAD) in international airspace close to the state of Alaska.

"The Alaskan Region of NORAD detected, tracked, positively identified, and intercepted four Russian aircraft entering and operating within the Alaska Air Defense Identification Zone on February 13, 2023,” NORAD said in a statement on Tuesday.

According to the statement, the Russian aircraft was still in international airspace. The statement added that Russian action in the region is routine and is neither seen as provocative nor a threat by the US.

The statement further stated that the Russian aviation activity is in no way connected to recent NORAD and US activities involving unknown flying objects over North America in the previous two weeks.

On Sunday, US Congressman Jack Bergman said that the US shot down unknown flying objects over lake Huron on Sunday, right near the border with Canada, marking the fourth taken down over North America in less than two weeks.
