KIEV, Ukraine — Ukrainian opposition leader Vitali Klitschko, after meeting with the country's beleaguered president, is warning that tempers are heating up and says the president must take action to resolve the country's political crisis.

Klitschko's meeting on Tuesday with President Viktor Yanukovych came as parliament held a session that took no action.

Two months of protests have put Yanukovych under substantial pressure. But he has made no moves to work with the opposition since last week, when he pushed parliament to pass a measure providing amnesty to many arrested protesters if demonstrators vacate buildings they occupy.

Protesters rejected that condition and continue to seek Yanukovych's resignation and early elections.

After the meeting, Klitschko said "the temperature of society is growing and I told the president we have to immediately take a decision."
