WASHINGTON, May 21 (Xinhua) -- Several Russian bombers and fighters were intercepted by U.S. F-22 fighter jets off the coast of Alaska on Monday, said the U.S. military on Tuesday.

Two of the Russian Tu-95 bombers were intercepted by two F-22s, and a second group of two Tu-95 bombers with two Su-35 fighters were intercepted later by two more F-22s, said the North American Aerospace Defense Command in a statement on Twitter.

The interception occurred at the Alaskan Air Defense Identification Zone (ADIZ) and the Russian warplanes remained in international airspace, the statement added.

In September, two Russian bombers were intercepted by two U.S. F-22 fighter jets near Alaska.
