Ukraine opposition seeks help from West

Ukrainian opposition leaders are due to meet the United States' top diplomat, John Kerry, a day after the US condemned the apparent torture of a protest leader who claims unidentified abductors "crucified" him.

Dmytro Bulatov, 35, who re-emerged on Friday after being missing for a week, said unidentified kidnappers beat him, sliced off part of his ear and nailed him to a door during his time in captivity.

The reported beatings and intimidation have stoked speculation that special security teams were roaming Ukraine and hunting down opposition activists.
