WASHINGTON (Sputnik) – On Friday, US media reported that a Russian Su-27 jet performed a "barrel-roll" over a US Air Force RC-135 reconnaissance plane in the Baltic Sea.
"The US aircraft was operating in international airspace and at no time crossed into Russian territory. This unsafe and unprofessional air intercept has the potential to cause serious harm and injury to all aircrews involved," Lt. Col. David Westover of the US Air Force said.
Westover said that the US aircraft was "flying a routine route in international airspace over the Baltic Sea [when it] was intercepted by a Russian SU-27."
Flyby incidents in the Baltic Sea have been a source of tension between Russia and the United States.
On April 13, the United States expressed concern after Russian Su-24 tactical bombers flew over the US guided missile destroyer Donald Cook in the Baltic Sea.
