'Very High' Chance Of Ending Violence One of Ukraine's main opposition leaders has said there is a "very high" chance of finding a way to end the violence and political unrest in the country. Arseniy Yatsenyuk, leader of the Fatherland party, made the comment after four hours of talks with President Viktor Yanukovych in Kiev. Former boxing champion Vitali Klitschko, leader of the Punch party, and nationalist leader Oleg Tyagnybok were also at the discussions. Riot police and protesters in the Ukrainian capital have been locked in a tense standoff following days of street battles which protesters say have left five people dead. We had the task of halting the bloodshed. The chance (of this) is very high," said Mr Yatsenyuk as he emerged with the other two leaders after the talks. President Yanukovych has also called an emergency parliamentary session - likely to be held on Tuesday - which will discuss the protesters' demands, which include the government's resignation and the scrapping of a new anti-protest law. Street battles have raged for days Prime Minister Mykola Azarov earlier accused opponents of attempting to stage a coup and dismissed demands for a snap election as "unrealistic." "A genuine attempt at a coup d'etat is being carried out," he said, while attending the World Economic Forum in Davos, Switzerland. Opposition leaders had urged "calm" ahead of Thursday evening's talks, but warned of fresh clashes if early elections were not called. Earlier in the day, Mr Yatsenyuk told a crowd of around 40,000 people in Kiev's Independence Square that he was ready to die for the cause. "If he does not go down that path then we will go forwards together and if it means a bullet to the head, then it is a bullet to the head," he said. Viktor Yanukovych, you have 24 hours. Take a decision. I have taken my decision. Mr Klitschko added: "Early elections will change the situation without bloodshed and we will do everything to achieve that." Opposition leaders address the protesters Activists claim that of the protesters killed in recent days, four were shot and one died in a fall. One of the dead was named locally as Serhiy Nihoyna. Prime Minister Azarov has said police are not carrying live ammunition and that opposition leaders should be held responsible for the deaths. Police and protesters have been turning an area at the heart of the city into a virtual war zone with demonstrators setting fire to barricades, hurling stones and Molotov cocktails, and police using tear gas, stun grenades and rubber bullets. Sky's Katie Stallard, in Kiev, said: "Protesters also burned tyres, mattresses, whatever they could find to keep going, and reinforcing barricades too. They have made homemade shields out of planks of wood and are rehearsing their tactical formations - how they plan to stand together and how they plan to protect themselves. The Interior Ministry said 73 protesters had been arrested and 53 of them were being investigated for "mass riots." It is a charge that was recently introduced and carries a jail sentence of up to eight years. The rioting intensified when some 200,000 took to the streets at the weekend in a show of anger over the new anti-protest laws rushed through by Mr Yanukovych. Discontent in Ukraine began last year when Mr Yanukovych refused to sign up to closer ties with the European Union in favour of a new accord with Russia. Meanwhile, Russia said it would not intervene in the crisis, according to President Vladimir Putin's spokesman Dmitry Peskov.
