Ukraine crisis: Sloviansk mourns pro-Russian activists

US Vice-President Joe Biden has said Russia must "stop talking and start acting" to defuse the Ukraine crisis.

Mr Biden urged Moscow to end its alleged support for pro-Russian militants.

The funerals have meanwhile taken place of three men shot on Sunday during a raid on a checkpoint manned by pro-Russian separatists near the flash point of Sloviansk.

Daniel Sandford reports from there.
