The United States Navy said on Friday that a Russian navy ship quote "aggressively approached" a U.S. destroyer in the North Arabian Sea.
That's according to the U.S. Navy's Fifth Fleet, which said in a tweet that the incident occurred on Thursday.
Video from the U.S. Navy captured five internationally recognized horn blasts signaling 'danger of a collision.'
The U.S. destroyer requested that the Russian ship alter its course in accordance with international maritime standards, and ultimately the Russian ship did comply.
But Moscow on Friday denied that one of its navy vessels had come dangerously close.
Russia's Ministry of Defense said in a statement that the U.S. Navy vessel had crossed the Russian ship's path, in an action it deemed "unprofessional" and accused the American ship of violating "maritime security norms."
