Washington (CNN) - Two Russian TU-95 Bear bombers were intercepted in international airspace off the coast of Alaska by two US F-22 Raptor fighter aircraft on Monday, the Pentagon confirmed to CNN.

The intercept, which was described by a US military official as safe and professional, took place about 100 miles from Kodiak Island after the Russian aircraft flew into the Alaskan Air Defense Identification Zone.

There was no cockpit-to-cockpit radio communication between the US and Russian pilots, the US official told CNN.
