BBC: Ukrainian MPs have voted to oust President Yanukovych and hold early presidential elections on 25 May. The vote came barely an hour after Mr Yanukovych said in a televised address that he would not resign. Protesters have walked unchallenged into the president's office and residential compounds.

The opposition is in effective control of the capital Kiev, with Mr Yanukovych now in the eastern city of Kharkiv, near the Russian border.
