The Russian destroyer Admiral Vinogradov engaged in "unsafe and unprofessional" behavior by sailing dangerously close to the US Navy Ticonderoga-class cruiser USS Chancellorsville, the US 7th Fleet said in a statement accompanied by photos and videos of the incident.

The Russians accused the American vessel of acting improperly, arguing that the USS Chancellorsville abruptly changed course and cut across the path of the destroyer.

Amid the back and forth over who is to blame for the latest US-Russia confrontation, eagle-eyed observers took note of something peculiar in the videos released by the Navy - what appears to be Russian sailors sunbathing shirtless, if not naked, as one appears to be, on the helicopter pad.

NPR reported the unusual Russian behavior in an article discussing the showdown between the Russian and US warships.

"In an odd sight, the videos show several Russian service members seemed to be sunbathing on an aft platform aboard the destroyer as it nears the American warship," the writer observed.

While Department of Defense and Navy officials noted the behavior, none were willing to speculate on the record about what exactly the Russians were doing or why.
