Russia orders exercises after Ukraine moves on separatists

More violence in eastern Ukraine has weakened still further the prospect of an end to the crisis as agreed at talks last week in Geneva.

There has been fighting between Ukrainian forces and pro-Russian separatists which has left five people dead.

Russia has begun fresh military exercises along the border in response and is again threatening "consequences".

BBC Correspondent Daniel Sandford has been to Sloviansk - which saw the worst of the fighting .
