Russia scrambled a fighter jet on Tuesday to intercept a nuclear-capable U.S. B-52 strategic bomber it said was flying over the Baltic Sea near its border, in an incident that had echoes of the Cold War.

The appearance of the B-52, a long-range bomber that first went into service in the 1950s, irked Moscow. A Russian Foreign Ministry official said the plane's appearance in Europe would not help ease tensions between the West and Russia. A former Russian Air Force commander called the move "disrespectful."

Russian air defense systems detected the U.S. bomber at around 1000 Moscow time as it was flying over neutral waters parallel to the Russian border and sent a Sukhoi Su-27 jet to intercept it, the Russian Defense Ministry said in a statement.
