KIEV, Ukraine (AP) — Opposition leaders in Ukraine are asking protesters to refrain from clashing with police for the next 24 hours, after at least two demonstrators were shot and killed in confrontations with police.

Emerging after three hours of talks with President Viktor Yaanukovych on Wednesday evening, opposition leader Arseniy Yatsenyuk said he gave the president until the following evening either to move to ease the political crisis or face popular rage.

“Tomorrow we will go forward together,” Yatsenyuk told a crowd of tens of thousands of demonstrators. “And if it’s a bullet in the forehead, then it’s a bullet in the forehead, but in an honest, fair and brave way.”

Prosecutors say two people died of gunshot wounds at the site of the clashes in Kiev on Wednesday, but the opposition says five people have died.

Two people were shot to death early Wednesday in anti-government protests in Ukraine, the first fatalities in the increasingly heated clashes with police in the streets of the Ukrainian capital, raising concerns that the movement is spiraling into a more dangerous phase of violence.

Medics at the site said a third man died after he fell from a high point near a sports arena at the site of clashes, but Natalia Vishnevska, spokeswoman for the city health department, said that man survived the fall and was being treated in the hospital.

The protesters’ deaths fueled fears that daily protests aimed at bringing down the government over its decision to shun the European Union for closer ties to Moscow and over human rights violations could turn even more violent.

Prosecutors said the two men were shot with live ammunition, and have opened a criminal investigation to determine who was responsible.

Prime Minister Mykola Azarov said the police did not have live ammunition and charged that opposition leaders should be held responsible for the deaths.

One of the victims has been identified by opposition leaders and doctors treating protesters as Sergei Nigoyan, a 20-year-old ethnic Armenian who came from the eastern city of Dnipropetrovsk in early December to join the protests on Kiev’s Independence Square, known as the Maidan. A video shows Nigoyan reciting poetry by the famed Ukrainian poet Taras Shevchenko, standing in the protest camp and clenching his fist in a sign of victory, as a Ukrainian yellow-and-blue flag flaps in the wind.

Respected Ukrainian journalist Kristina Berdinskikh, who has been profiling protesters for several weeks, interviewed Nigoyan in early January.

“I saw on TV what is happening on the Maidan, I didn’t sleep at night, I was following the news,” Nagoyan told Berdinshkikh, according to a transcript she posted online. “Then I decided to come. This is also my future.”

The mass protests erupted after Yanukovych spurned a pact with the European Union in favor of close ties with Russia, which offered him a $15 billion bailout. They swelled to hundreds of thousands after a small peaceful rally was violently broken up by police. Seeing the government ignore their demands and opposition leaders unable to present a coherent plan or even select a single leader, radical protesters have clashed with riot police in Kiev since Sunday.

The deaths came on the fourth day of violent street battles between protesters hurling fire bombs and stones and police firing back with tear gas, stun grenades and rubber bullets. The bodies were found before police moved to tear down protesters’ barricades near official buildings in central Kiev and chased demonstrators away.

Helmeted riot police moved in on hundreds of protesters, dismantling the barricades, beating many with truncheons and firing shots at some. One man was attacked by over a dozen policemen, was made to take off his winter jacket and dragged away, where he was beaten again. Dark smoke from burning tires billowed in the air and an armored vehicle was seen near police lines.

The police drove demonstrators down a hill toward the main protest site on Independence Square, where protesters have set up an extensive tent camp and rallied around the clock since November. There was no immediate police move on the main camp.

Oleksandr Turchynov, one of the opposition leaders, called on Ukrainians to rush to the center of Kiev to defend their country. “Ukraine will not be a dictatorship, it will be an independent, European country. Let us defend Ukraine!”

The U.S. Embassy said it was revoking the visas of some Ukrainian officials linked to the violence and was considering further action. The embassy would not name the officials, citing privacy laws. The EU condemned the violence and said it was also considering action against the Ukrainian government.

After several days of refusing face-to-face talks, Yanukovych met Wednesday with three main opposition leaders for several hours of talks to negotiate a solution.

The protests were the biggest since the peaceful 2004 Orange Revolution, which annulled Yanukovych’s fraud-tinged victory in a presidential vote and forced a new vote that brought his pro-Western rival to power. The current protests were also largely peaceful for nearly two months, but turned violent after Yanukovych, elected in 2010, pushed through sweeping anti-protest legislation and ignored all the protesters’ demands. The deaths mark a turning point in the stand-off that could lead to more violence.

“Look, the deaths and the injuries speak to the actions of those in power. They’ve crossed the line,” said Andriy Kolosovich, 20, whose was injured in the legs by a stun grenade and was being treated in a nearby medical unit set up by protesters.

The police move on the barricades came on the same day when much of international attention was focused in Switzerland, where peace talks aimed at ending Syria’s war began Wednesday.
