Two men captured by Ukrainian troops on Saturday have confessed to being members of the Russian armed forces, a report by European mediators says.
The pair were interviewed at a military hospital in Kiev by members of the Organization for Security and Co-operation in Europe (OSCE).
“They were armed but had no orders to attack,” the security body said.
Russia has not responded to the latest claims, but has previously said the two men were no longer serving soldiers.
The men had travelled to Ukraine on a “reconnaissance mission”, according to the OSCE.
“One of them said he had received orders from his military unit to go to Ukraine. He was to ‘rotate’ after three months. Both of them said they had been to Ukraine ‘on missions’ before,” it added.
“One of them stressed repeatedly that there were no Russian troops involved in fighting in Ukraine.”
