MIAMI • US Secretary of State John Kerry has condemned as dangerous and provocative a military encounter in the Baltic Sea that the United States has described as a simulated attack on a US destroyer by two Russian warplanes.
"We condemn this kind of behaviour. It is reckless. It is provocative. It is dangerous. And under the rules of engagement that could have been a shoot-down," Mr Kerry said on Thursday in an interview with CNN Espanol and the Miami Herald.
"People need to understand that this is serious business and the United States is not going to be intimidated on the high seas. We are communicating to the Russians how dangerous this is and our hope is that this will never be repeated."
The repeated flights by the Sukhoi Su-24 bombers on Tuesday, which also flew near the ship, the USS Donald Cook, a day earlier, were so close they created wake in the water, a US official said on Wednesday.
It was one of the most aggressive interactions between the two former Cold War foes in recent memory, the official said on condition of anonymity, although the planes carried no visible weaponry.
A Russian KA-27 Helix helicopter also made passes around the vessel, taking pictures.
In Moscow, Interfax news agency quoted Russian Defence Ministry spokesman Igor Konashenkov as saying on Thursday that the crews of the Russian bombers that flew near the US destroyer respected all safety rules.
State Department spokesman John Kirby said Mr Kerry will raise the incident with Russian Foreign Minister Sergei Lavrov.
White House spokesman Josh Earnest told reporters at a daily press briefing that Washington had raised its concerns with Russian officials. "I can tell you that that communication has occurred, and we'll seek to resolve our differences through well-established military channels," he said.
