The U.S. military scrambled a pair of F-22 stealth fighters Monday night to intercept two Russian long-range bombers that flew close to Alaska, a Pentagon official said Tuesday.

The Russian TU-95 "Bear" bombers are capable of carrying nuclear weapons, but there was no indication the planes were armed, and the bombers did not violate U.S. airspace, the official said.

The U.S. Air Force F-22s visually identified the plane and briefly flew alongside, before the Russian bombers changed course, and flew away from the U.S.

The interception was conducted a "safe and professional" manner, the official said, and there was no violation of any international norms.
