A sea drone self-destructed near an oil terminal in Romania's Black Sea port of Constanta on Friday, without causing casualties, as Ukraine said Russia jammed the vessel causing it to drift off course.

The explosion was the second major incident in a populated area in Romania on NATO's eastern flank within a week as the spillover threat from the war in Ukraine increases.

Ukraine's navy said one of its drones lost control in the Black Sea as a result of Russian electronic warfare. It contacted Romania to warn them and prevent casualties, it said.

Romanian Defence Minister Radu Miruta said that warning allowed a timely evacuation.
