Klitschko's top allies, who stood by his side at the peaceful rally earlier in the day, didn't show up at the site of the clashes for the most of the day. Instead, they called for a peaceful means of protest from nearby Independence Square and condemned the clashes.
"No power in the country is worth losing at least one human life," protest leader Arseniy Yatsenyuk said from the stage at the central square as the clashes dragged late into the evening a few hundred meters away. "That is why I condemn the violence that took place just now."
Scores of opposition leaders and journalists have been attacked, harassed and prosecuted, since the anti-government protests started Nov. 21.
