According to him, the US continues to support the deployment of the UN peacekeepers to Donbas

U.S. Special Envoy to Ukraine Kurt Volker claimed that he personally ascertained that the combat actions in the east of Ukraine became the consequence of the Russian intervention as he reported on Twitter.

"As I saw on my recent trip, there is a hot war in eastern Ukraine that has created a grinding, degrading humanitarian crisis all caused by Russia’s intervention," he wrote.

Volker added that the US continues to support the deployment of the UN peacekeepers to Donbas to simplify the implementation of the Minsk Agreements.

"But Russia’s proposal for an OSCE “protection force” is a non-starter," he added.

Earlier U.S. Special Envoy to Ukraine, Kurt Volker claimed that the ethnic Russians participate in the Donbas Conflict on both sides. He noted that Russia's President Vladimir Putin has some guidance and possibilities to 'present himself in the best light' toward the situation at the east of Ukraine.

Also, German Foreign Minister Heiko Maas said that the ministers of the Normandy Four during the talks in Berlin paid special attention to the issue of deploying the UN mission in the east of Ukraine.
