The events in the eastern city of Donetsk are the latest episode in the ongoing crisis in Ukraine provoking fears that Moscow could be orchestrating a second Crimea scenario in Ukraine's east.
Russian foreign minister Sergey Lavrov said his country is not destabilising Ukraine. In a piece in the Guardian newspaper, Lavrov accused the EU and US of pursuing what he called an unproductive and dangerous policy in the region.
In Washington, the US has warned that any move by Russia into eastern Ukraine would be a very serious escalation that could bring further sanctions.
