Russia said Sunday it scrambled fighter jets to intercept two U.S. military long-range bomber aircraft that approached the Russian border over the Barents Sea in the Arctic.

鈥淭he crews of the Russian fighters identified the aerial target as a pair of U.S. Air Force B-52H strategic bombers,鈥 Moscow鈥檚 defense ministry wrote on the social media platform Telegram, specifying that the planes scrambled were MiG-29 and MiG-31 fighters.

鈥淎s the Russian fighters approached, the U.S. strategic bombers turned away from the State Border of the Russian Federation,鈥 the ministry said.

The U.S. routinely carries out flights over international waters. Moscow has recently responded more aggressively to the exercises, accusing the U.S. in June of using its reconnaissance drone flights over neutral waters in the Black Sea to help Ukraine strike Russian-occupied Crimea.

Last month, Moscow warned of a 鈥渄irect confrontation鈥 between Russia and NATO, and Russia鈥檚 defense minister ordered officials to prepare a 鈥渞esponse鈥 to U.S. drone flights over the Black Sea, in an apparent warning it may take forceful action to ward off the American reconnaissance aircraft.

Washington and Moscow have clashed before over the issue. In March 2023, a Russian Su-27 fighter jet damaged a U.S. MQ-9 Reaper drone, causing it to crash into the Black Sea. It was the first direct clash between Russian and U.S. forces since the Cold War.

A repeat of such a confrontation could further fuel tensions over the war in Ukraine.
