WASHINGTON, D.C.: Fighter jets from South Korea and the United States intercepted two Russian warplanes after they flew near a US aircraft carrier operating off the Korean peninsula, officials said Thursday. White House spokesman Josh Earnest said the USS Ronald Reagan — a massive, nuclear-powered supercarrier — was involved in a military exercise with South Korean partners when two Russian Tu-142 Bear aircraft flew past the ship. The two Russian Tu-142 Bear aircraft were flying about a mile from the carrier at an altitude of 500 feet on Tuesday, Pentagon spokesman Captain Jeff Davis said. He said there was no evidence the Russian planes posed a direct threat. Tu-142 Bears are primarily reconnaissance and anti-submarine aircraft. Still, the carrier scrambled four F/A-18 fighters to intercept and escort the Russian aircraft, he said.
