Policia y manifestantes ucranianos chocan violentamente en Kiev

In Ukraine, authorities issued a deadline for protesters to end clashes with police, threatening to restore order if disturbances continued. At least four people died in the Tuesday confrontations. Opposition lawmakers accused the government of blocking constitutional reforms that would reduce presidential powers, with a session to discuss these changes delayed. Protesters hurled stones at police outside Parliament, who responded with tear gas. The violence dimmed hopes for resolving the three-month political crisis. Opposition parties accused President Yanukóvich's party of obstructing reforms that would empower Parliament, though Yanukóvich remains popular.
