Ukraine amnesty comes into force after protesters retreat
An amnesty for anti-government protesters in Ukraine has come into force after protesters ended their occupation of government buildings.
The prosecutor's website said criminal charges would be dropped after the opposition left Kiev city hall and other locations.
Protesters had held some of the buildings for more than two months.
But a sprawling tent city remains in a central square, where some denounced the decision to end the occupations.
A group of radical protesters are reported to have blocked the entrance to the City Hall building, shortly after other opposition supporters vacated it.
They are not thought to have entered the building itself.
The protests started in November when President Viktor Yanukovych abandoned plans to sign a far-reaching association agreement with the EU.
Instead, he advocated closer trade relations with Russia, which dominated Ukraine for centuries until the fall of the Soviet Union in 1991.
Protesters left City Hall on Sunday morning.
The Swiss ambassador in Kiev entered the building soon afterwards to help transfer it to the control of the authorities.
Switzerland currently holds the rotating presidency of the Organisation for Security and Cooperation in Europe.
The BBC's David Stern in Kiev says protesters also partially dismantled barricades on a street in the centre of the capital.
By ending their occupations, the protesters met the government's conditions under an amnesty law.
On Friday authorities freed the last of 243 prisoners who were arrested during the unrest.
Mr Yanukovych passed an amnesty law last month and agreed to negotiate with the opposition after at least four people were killed in protests.
The amnesty does not extend to all activists, since it covers a limited period in the three-month old protest movement, from 27 December to 2 February.
At the latest mass rally in Independence Square on Sunday, some protesters were highly critical of the decision to end the occupations.
"It's a bad decision... We can't trust the authorities, they're crooks. The opposition is making a big mistake," 56-year-old Volodymyr Penkivski, who had travelled from northern Ukraine, told AFP news agency.
"Yanukovych will take other [protesters] hostage. We can't beat a retreat. Otherwise we will all go to prison."
But opposition leader Vitaly Klitschko said it was the right choice.
"When you're behind bars, you don't have the same outlook," he said, according to AFP.
Some of those arrested had been facing charges carrying sentences of up to 15 years in jail.
Many opposition members continue to call for Mr Yanukovych's exit from Ukrainian politics.
"The only subject of negotiation with Yanukovych is the conditions of his departure," jailed opposition leader Yulia Tymoshenko said on Saturday.
She went on to accuse the Ukrainian president of being under the control of Russia's Vladimir Putin, his major international backer.
On Tuesday, opposition deputies are expected to try to pass legislation that would return the country to its 2004 constitution, which would limit Mr Yanukovych's powers and introduce early presidential elections, our correspondent says.
