Military authorities say US Air Force and Canadian fighter jets were scrambled to escort two Russian bombers that were traveling near the North American coastline.
The North American Aerospace Defense Command says two F-22 and two CF-18 fighter jets identified two Russian Tu-160 Blackjack strategic bombers that were entering an area patrolled by the Royal Canadian Air Force on Saturday morning.
There were no reports of conflict between the Russian and the US and Canadian jets.
