The North American Aerospace Defense Command says two of its F-22s intercepted two Tupolev Tu-95 strategic bombers inside the Alaska Air Defense Identification Zone on Monday.
A short time later, two additional Tu-95s and two Sukhoi Su-35 fighters were identified and intercepted by two other NORAD F-22s.
A U.S. E-3 Sentry maintained overall surveillance on the operation. The Russian aircraft remained in international airspace.
