Russia-backed separatist leader says Moscow should launch next phase of Ukraine campaign

The Russian-backed separatist leader of the Ukrainian breakaway region of Donetsk said on Tuesday that Moscow should launch the next stage of its military campaign in Ukraine after reaching the region's frontiers, RIA news agency quoted him as saying.

Denis Pushilin, the leader of the self-proclaimed Donetsk People's Republic, said on a Russian talk show broadcast online that the next phase of Russia's military intervention was crucial following security incidents outside the region.

He cited blasts that hit the Moldovan breakaway region of Transdniestria bordering Ukraine on Monday, as well as Russian allegations of shelling of its border regions by Ukrainian forces.

"The pace at which the (military) operation reaches our borders is important to us in order to launch its next phase, which is needed after what we witnessed in Transdniestria and Russia's border regions," RIA news agency quoted Pushilin as saying.

Russia sent tens of thousands of troops into Ukraine on Feb. 24 in what it called a special operation to degrade its southern neighbour's military capabilities and root out people it called dangerous nationalists.

Ukrainian forces have mounted stiff resistance and the West has imposed sweeping sanctions on Russia in an effort to force it to withdraw its forces.
