One of the targets entered Romanian airspace, but radar contact was lost 16 kilometers southeast of the commune of Chilia Veche, over an uninhabited area. The air raid alert was lifted at 2:48 a.m.
Romania’s Defense Ministry said experts would head to the area in the morning to conduct a search operation.
