Ukraine clashes: Opposition ready for 'bullet to head'

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.
Prime Minister Mykola Azarov said compromises "might be possible", but the opposition should avoid ultimatums.
Another opposition leader, Arseniy Yatsenyuk, said those responsible for the country's crisis should be brought to account, and he was prepared to face ''a bullet to the head'' if that did not happen.
