In Ukraine anti-government protesters have smashed their way into Kiev's city hall, while others have tried to break through police lines to get to the presidential office.
The BBC's Steve Rosenberg says the incidents happened "on the fringes" of the main anti-government rally being held in Independence Square, where thousands are calling for President Victor Yanukovich to stand down.
Demonstrations against Mr Yanukovich's administration began a week ago, in response to his refusal to sign an association agreement with the European Union.
