KIEV (AFP) - Ukraine's opposition agreed on Thursday to observe an eight-hour truce in clashes with security forces after five days of deadly fighting but threatened to go on the attack if the government failed to agree concessions.
Opposition leader and world boxing champion Vitali Klitschko brokered the truce after talks with radical protesters and armoured security forces on the frontline of the clashes, saying the ceasefire should hold while he conducts talks with President Viktor Yanukovych.
The fighting, which activists say has left five protesters dead, raged into the night at the epicentre of the clashes on Grushevsky Street in central Kiev, with demonstrators hurling Molotov cocktails and security forces using stun grenades.
The bloody clashes, which have turned parts of the usually placid capital into a war zone, marked a new peak in tensions after two months of protests over the government's failure to sign a deal for closer integration with the European Union under Russian pressure.
"By 8:00 pm (1800 GMT) I will return to you and inform you of the result of the talks," the Interfax Ukraine news agency quoted Mr Klitschko as telling the protesters.
"Keep the barricades in place but (be) calm until the talks finish," he added.
An AFP correspondent at the scene of the fighting on Grushevsky Street confirmed that there had been a pause in clashes and that the truce appeared to be holding.
Mr Klitschko and other opposition leaders are due to meet Mr Yanukovych at the presidential administration this afternoon for a second round of talks.
The opposition has said the president must agree to three key demands - the holding of snap presidential elections, the resignation of the government and the annulment of anti-protest laws passed last week - for a compromise to be reached.
The protesters have marked their frontline with a semicircle of burning tyres which have sent rancid plume of black smoke billowing into the Kiev sky and are visible throughout the city.
However under the terms of the truce, protesters allowed police to douse the fires with water cannon and now only white smoke was rising at the scene.
