Many videos are emerging on social media of the scale and extent of the violence. Here's one that appears to show a military vehicle ramming into a barricade.
Ukrainian Olympic Committee President Sergei Bubka is urging both sides in Ukraine's political crisis to halt the violence, saying it is putting the country “on the brink of catastrophe."
Bubka, a former Olympic pole vault champion, issued his call on Wednesday after clashes between police and antigovernment protesters in Kyiv left 25 people dead.
In a statement, Bubka said he was "shocked” by the dramatic development occurring in his country at a time when Ukrainian athletes were competing “peacefully and with honor" at the Winter Olympics in Sochi.
Meanwhile, the Ukrainian Olympic Committee said the Ukrainian delegation in Sochi led by Bubka had asked the International Olympic Committee if their athletes could wear black bands in competition to remember the dead.

RFE/RL's live feed from Kyiv is now back up and running:
The recent events in Ukraine have shown "the escalation of violence and a massive use of firearms by the extremist groups. In many parts of the country, public authorities, military installations and depots with munitions are being seized. Court buildings are burning, the vandals are destroying private property and killing peaceful civilians,” the Ukrainian Security Service head, Aleksandr Yakimenko, said in a statement.
According to Yakimenko, “over the last day more than 1,500 firearms and 100,000 rounds of ammunition have come into the hands of criminals.”
Reacting to the “conscious, purposeful use of force by means of arson, killings, kidnapping and terrorizing people,” which Yakimenko treats as “terrorist acts,” the Security Service and Anti-terrorist center of Ukraine have decided to launch a counter-terrorist operation.
The Security Service head then urged all Ukrainians to stay calm and maintain peace and order. Special measures to reinforce public security and border security are being taken.

In what appears to be a big development, the executive committee of Lviv's regional council has announced in a statement that it is taking power in the region into its own hands:
"The regime has begun active military action against people […] Dozens of people have been killed in Kyiv and hundreds have been wounded […] Fulfilling the will of society, the executive committee of the Lviv region's council, the People's Rada, is assuming full responsibility for the fate of the region and its citizens," the statement says.
The document reiterates that the main function of the executive committee is to maintain law and order in the region and help send activists to Kyiv and provide the Maidan activists with everything they need:
"The lawfully elected local councils and the executive committees created by them remain the legitimate authorities in the Lviv region. The majority of the district police departments have already announced their decision to take the side of the people of Ukraine and report to the executive committee of the Lviv region's council."
