KIEV, Ukraine -- Ukraine's president gave in to pressure from European diplomats and offered concessions Friday to defuse a crisis that has divided his country and left scores dead. Shots rang out near the protest camp and a skeptical opposition massed in central Kiev, divided over what to do next.
CBS News correspondent Holly Williams reports from Kiev that there were scuffles Friday morning in Ukraine's Parliament as opposition members called for snap presidential elections. The protesters in Kiev's Independence Square told CBS News that they were staying put until Yanukovych was removed from power.
European foreign ministers had stayed up all night in Kiev trying to negotiate an end to the standoff, prompted when the president aborted a pact with the European Union in November in favor of close ties with Russia instead.Small groups of protesters advanced toward the president's office, torching one truck and seizing two others. Scuffles broke out between a few dozen radicals who wanted to attack the building and more moderate protesters.
A group of police officers from western Ukraine arrived on Independence Square to show their support for the opposition, and one told The Associated Press that they had arms.
Yanukovych gave no time frame for new elections, and it's unclear whether his belated concessions will be enough to satisfy protesters who have occupied a piece of Kiev and government buildings around the country in a nationwide battle over the identity of their country.The U.S., Russia and European Union are deeply concerned about the future of Ukraine, a nation of 46 million that has divided loyalties between Russia and the West. Shots rang out again Friday near the protesters' camp in Kiev, a day after the deadliest violence in Ukraine's post-Soviet history. It is unclear who was targeted and whether anyone was hurt or injured in Friday's incident.
"As the president of Ukraine and the guarantor of the Constitution, today I am fulfilling my duty before the people, before Ukraine and before God in the name of saving the nation, in the name of preserving people's lives, in the name of peace and calm of our land," the president said in a statement on his website.
Yanukovych also promised constitutional reforms trimming presidential powers, a key demand of protesters.
The opposition has rejected similar invitations to join the government in the past, saying that constitutional reform giving parliament greater powers has to be passed first.
On the early elections, a Yanukovych ally earlier said that they would be held in December instead of March - not soon enough for many protesters enraged by police violence.
Lawmaker Inna Bogoslovskaya, allied with the opposition, told the AP that December is too late for elections. "After 77 corpses yesterday ... that changes the stakes," she said. "The Maidan (protest movement) demands immediate resignation of the president instead of early elections."
Protesters will not abandon occupied buildings until after the constitution is changed, she added.
Polish Foreign Minister Radoslaw Sikorski, who is involved in the negotiations in Kiev, called for calm and said he was going to meet with protesters on the Maidan. He tweeted that it's a "delicate moment for the settlement and all must remember you don't get 100 percent in a compromise."
The German Foreign Ministry tweeted that Foreign Minister Walter Steinmeier and Sikorsky were to hold more talks with opposition leaders and protesters Friday.
All this was not enough for some protesters, who accused the president of trying to buy time and want him out immediately.
"We don't believe him. He has cheated the people before. He declared a truce, and then there was shooting," said Valentin Mashul, manning a table with a collection box for money donations for the protesters.
"It's completely not enough," said protester Anton Gusev, standing at one of the barricades near city hall. Referring to the election date, he said, "December or March - what difference does it make?"
At the city hall barricade, protesters were busily organizing stacks of tires. The street was crowded with people heading toward the central square.
Several regions in the west of the country are in open revolt against the central government, while many in eastern Ukraine back the president and favor strong ties with Russia, their former Soviet ruler.
In a sign of the high tensions, armed law enforcement officers tried to enter parliament Friday morning during a debate over measures to end the crisis. Shouting lawmakers pushed them out.
The report of a deal followed the worst violence yet in the confrontation between the government and protesters.
Protesters advanced on police lines in the heart of the Ukrainian capital on Thursday, prompting government snipers to shoot back and kill scores of people in the country's deadliest day since the breakup of the Soviet Union a quarter-century ago.
A statement on the website of the Health Ministry said 77 people had been killed between Tuesday morning, when the violence began, and Friday morning. The statement said 577 people had been wounded and 369 hospitalized. Opposition sources claimed at least 70 on their side were killed Thursday.
There was no way to immediately verify the figures.
Protesters across the country are upset over corruption in Ukraine, the lack of democratic rights and the country's ailing economy, which just barely avoided bankruptcy with the first disbursement of a $15 billion bailout promised by Russia.The violence is making Ukraine's economic troubles worse. Ratings agency Standard & Poor's downgraded Ukraine's debt rating Friday, saying the country will likely default if there are no significant improvements in the political crisis, which it does not expect.
