Witnesses in the Ukrainian capital say at least 22 people have been killed in fresh clashes that erupted between anti-government protesters and police, hours after President Viktor Yanukovych announced a truce with opposition leaders.
Some of those killed were reportedly shot by government snipers. Ukraine's Interior Ministry, meanwhile, reported that three police officers were killed Thursday. It said more than 50 police personnel had been hospitalized during the day, 30 of them with gunshot wounds.
The latest reported death toll is in addition to the 28 people the health ministry says were killed in clashes earlier this week after riot police swarmed a makeshift protest camp in Kyiv.
The violence comes as three European Union foreign ministers met with President Yanukovych in Kyiv to discuss the crisis. Earlier reports said the talks were called off due to the renewed violence. Later in the day, the EU is holding an emergency meeting in Brussels to discuss possible sanctions against those responsible for the unrest.
Clashes between anti-government protesters and police have escalated this week. In addition to the deaths, nearly 300 people have been hospitalized -- including 88 police officers, six journalists, and a member of parliament.
President Yanukovych and the leaders of anti-government protests had agreed on a truce Wednesday. A statement on President Viktor Yanukovych's website said it is aimed at "ending the bloodshed and stabilizing the situation ...in the interests of social peace." It did not provide details.
Hours before the truce was announced, the president fired his army chief and Ukraine's military declared a nationwide crackdown on what it called "extremist groups." Mr. Yanukovych -- the target of the protests -- offered no explanation for the dismissal.
In announcing the "anti-terrorist" operation, the Interior Ministry said protesters elsewhere in the country had overrun government arms depots and seized weapons and munitions. Local media quoted officials as saying they fear those stockpiles are being transported to the capital for use by protesters trying to force Mr. Yanukovych from power.
Security service chief Oleksandr Yakimenko said Wednesday that municipal buildings, security offices and arms depots had been raided around the country. He said 1,500 firearms and 100,000 rounds of ammunition wound up "in the hands of criminals" over the previous 24 hours.
Elsewhere Wednesday, the United States, Germany and France issued strong statements of protest against the violence.
U.S. President Barack Obama warned that the United States holds the Ukrainian government "primarily responsible" for dealing with the protests in an appropriate way. Washington also imposed visa bans on 20 senior government officials believed responsible for the crackdown, and issued a travel warning for U.S. citizens in Ukraine.
Separately, German Chancellor Angela Merkel, speaking in Paris alongside French President Francois Hollande, called for "quick and targeted sanctions" against those responsible for the violence.
Anti-government protests have been building for weeks, with activists calling for Mr. Yanukovych's ouster after he backed away from a trade deal with the European Union in favor of closer ties with Russia.
In Moscow, Kremlin spokesman Dmitry Peskov condemned the deadly Ukraine protests as a "coup attempt." He denied claims President Vladimir Putin was giving advice to Ukraine's president on how to handle the crisis and reiterated Moscow would not interfere with Ukraine's internal affairs.
