"On two occasions, on 9 and 14 of May respectively, an ambulance with Russian Federation registration plates entered the BCP from the Russian Federation, before returning less than one hour later without crossing the border.

The OT was able to observe one paramedic and one woman in civilian clothes in the vehicle," it said.

According to the OSCE, at 09:56 on May 10, at the Donetsk BCP, a convoy of six vehicles, four civilian cars and two police escorts arrived from the Russian Federation. "The vehicles underwent border formalities and crossed to Ukraine at 10:20. One of the police cars went back to the Russian Federation immediately. The OT could observe passengers in civilian clothes. During the convoy crossing, Russian Federation border guards stopped traffic inside the BCP," it said.
