Six ships have arrived in the Romanian Black Sea port of Constanta to take part in NATO sea exercises this weekend.

The three-day training called SNMG-2 will be led by Rear Admiral Brad Williamson of the U.S. Navy, NATO said in a statement Friday.

Participating ships include USS Vicksburg, as well as a German auxiliary ship and frigates from Canada, Turkey, Italy and Romania.

The exercises are part of a regularly scheduled deployment to the region to assure allies of NATO's commitment to collective defense.
