Russian diplomat says Kiev must restrain its volunteer battalions acting in Donbas

MOSCOW, April 3. /TASS/. Pro-Kiev volunteer battalions acting in the country’s east are the source of major problems amid international efforts to resolve the ongoing conflict in the former Soviet state, Russia’s OSCE envoy Andrey Kelin said on Friday.

"They [the Ukrainian authorities] must bring them to order and discipline or the problems will continue emerging," Kelin said.
