The BBC's Daniel Sandford has described a scene of "pretty serious devastation" in Kiev after pro-EU protesters clashed with police all night.
Ukraine's President Viktor Yanukovych has agreed to negotiate with the protesters and opposition leaders after the violent clashes.
He said a cross-party commission would be set up on Monday to try to resolve the deepening crisis. Opposition leaders confirmed this.
