This from the BBC:
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.
Notice the difference in tone?
Opposition: ultimatum, attack
Regime: compromise, might be possible, should avoid
Does that not say in all?
In the meantime, some more photographs of the recent events:
