Kiev: Ukraine's opposition on Thursday vowed further protests after defiantly rejecting an amnesty bill to free activists and ease the ex-Soviet country's worse crisis since independence.
The parliament passed an amnesty bill late Wednesday with backing from the ruling Regions Party, but the opposition rejected its conditions and a breakthrough appeared unlikely.
President Viktor Yanukovych has granted several concessions to protesters who have packed the centre of Kiev for the last two months, including accepting the resignation of Prime Minister Mykola Azarov. But the opposition wants the head of state to go.
EU foreign policy chief Catherine Ashton said after meeting Yanukovych that it was time for "real dialogue" to start and for "the violence and intimidation" to stop.
In a move that is likely to complicate matters further, Russian President Vladimir Putin said on Wednesday that Moscow would wait until a new government is formed in Ukraine before it considers releasing a crucial $15 billion bailout package for Kiev in full.
Analysts say the Kremlin may back out of the deal if it saw a staunchly anti-Russian government come to power in Ukraine, and the EU may end up having to bail out the former Soviet nation.
Three activists were shot dead in clashes in Kiev last week, but tensions have calmed somewhat since negotiations between the government and the opposition gained traction.
However, there still appears to be no easy way out of a crisis which will influence the future orientation of the nation of 46 million people sandwiched between Russia and the EU.
Putin on Wednesday discussed the crisis with German Chancellor Angela Merkel, the Kremlin said, stressing that "any outside interference is unacceptable."
Merkel for her part told Putin to push for a "constructive dialogue" to defuse the crisis in Ukraine, her office said.
'On the brink of civil war'
Protesters, some from right-wing radical groups, remained camped out in much of the city centre of Kiev and have now erected wooden watchtowers at their barricades. They are still occupying key municipal buildings including the Kiev city hall.
Underlining the gravity of the crisis, Ukraine's first post-independence president Leonid Kravchuk on Wednesday warned that the country was "on the brink of civil war".
"It is a revolution. It is a dramatic situation in which we must act with the greatest responsibility," said Kravchuk, who was president from 1991 to 1994.
The opposition did not vote for the amnesty bill as it is unhappy that the law is conditional on protestors vacating buildings they have occupied in Kiev.
The majority Regions Party backed the law after a rare closed-door meeting at parliament with Yanukovych, who reportedly threatened early parliamentary elections if they did not support it.
A total of 232 deputies voted for the bill and 11 against, but 173 MPs present in the parliament did not vote.
The amnesty will only be enforced after the Prosecutor-General confirms protesters have left all government buildings across the country.
Svoboda (Freedom) party leader Oleg Tyagnybok said that parliament had essentially adopted a law about "hostages" as the dozens arrested during the crisis would now be held until buildings are freed.
"The authorities have now admitted they take hostages like terrorists do, so that they can then barter over them," he was quoted as saying.
"Don't believe that the opposition will give up the Maidan," he said, referring to Kiev's Independence Square at the heart of the protests.
The UDAR (Punch) party leader and world boxing champion Vitali Klitschko warned: "Instead of lowering the temperature in society, this is going to raise it."
Dozens of activists have been arrested since clashes broke out January 19, both in Kiev and in the provinces, where activists have stormed regional administration buildings.
