WASHINGTON, May 22 (Xinhua) -- For a second time in two days, U.S. warplanes on Tuesday intercepted Russian military planes off the coast of Alaska, the U.S. military said on Wednesday.

After being intercepted by two U.S. F-22s, two Russian Tu-95 bombers which entered the Alaskan Air Defense Identification Zone (ADIZ) exited and then re-entered the Alaska ADIZ with two Su-35 fighter jets, said the North American Aerospace Defense Command (NORAD) in a statement.

The Russian aircraft remained in international airspace, not entering U.S. or Canadian sovereign airspace, NORAD said.

It was the second time in two days that Russian warplanes were intercepted by the U.S. air forces. On Monday, a total of four Russian bombers and two fighters were intercepted by U.S. F-22 fighter jets off the coast of Alaska.
