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.
NORAD says it uses radar, satellites and fighter aircraft to patrol the skies and monitor aircraft entering US or Canadian airspace.
NORAD tweeted: “An E-3 AWACS, 2x F-22, 2x CF-18 fighter jets from NORAD positively identified 2x Russian Tu-160 Blackjack strategic bombers entering the Canadian Air Defense Identification Zone on January 26, 2019.
The US Air Force sent planes from their air base in Alaska.
