A joint naval exercise of U.S., Bulgarian and Romanian naval forces in the Black Sea has started, the Bulgarian navy said on Wednesday, March 12, according to Reuters.

The USS Truxtun, a U.S. guided-missile destroyer with about 300 crew and part of the U.S. Sixth Fleet headquartered in Italy, joined the maneuvers with Bulgarian naval frigate Drazki and three Romanian vessels in the Black Sea.

"This time the exercise has begun as planned," Lieutenant-Colonel Dimitar Titev told Reuters. The drills were delayed by one day on Tuesday due to bad weather.

Bulgarian Defence Minister Angel Naydenov said that the Ukrainian ambassador to Sofia, Mikola Baltaji informed him that a joint BLACKSEAFOR naval exercise, that was to be led by Ukraine between March 28 and April 15, was cancelled.
