Ukrainian opposition leaders have issued an ultimatum to President Viktor Yanukovych, after talks failed to resolve the political stalemate.

Vitali Klitschko said he would lead pro-EU protesters "on the attack" in the capital, Kiev, if the government refused to call snap elections.

Two activists were killed in clashes with police in Kiev on Wednesday.

Ukrainian Prime Minister Mykola Azarov told the BBC provocateurs were probably to blame for their deaths, not the police.
