A pair of Russian supersonic, nuclear-capable bombers buzzed North America Saturday, forcing American and Canadian fighter jets to scramble and intercept them, the U.S. military said.

The two Russian Tu-160 Blackjack bombers “remained in international airspace,” but were escorted by two U.S. Air Force F-22 fighter jets and two Canadian CF-18 jets, according to a statement from the North American Aerospace Defense Command, better known as NORAD.

The U.S. jets flew from an Air Force base in Alaska.

The Russian bomber flight near North America — the first known flight this year — coincides with the visit of NATO’s Secretary General Jens Stoltenberg to Washington to meet Secretary of State Mike Pompeo, acting Defense Secretary Pat Shanahan and national security adviser John Bolton.
