From the dingy basement of a decaying apartment block on the outskirts of Simferopol, Crimean parliament deputy Sergei Shuvainikov is leading the fight to defend the ethnic Russians of this strategic Black Sea peninsula. In an office festooned with banners showing a map of Crimea overlaid with a World War II medal featuring the communist hammer and sickle and the slogan "In union with Russia," the voluble Shuvainikov spills out a litany of alleged assaults on the Russian language and Russian culture in Ukraine.

Ukraine's new interim President Oleksandr Turchynov has said the country will focus on closer integration with the EU. Mr Turchynov was appointed following the dismissal of President Viktor Yanukovych by MPs on Saturday. Mr Yanukovych's rejection of an EU-Ukraine trade pact triggered the protests that toppled him. The interim president also said he was "ready for dialogue" with Russia, which has backed Mr Yanukovych.

With Ukraine's parliament dismantling the last vestiges of ousted President Viktor Yanukovych's government, the Obama administration warned Russia against sending troops into the country and told Moscow that it should allow Ukrainians to freely determine their own future. Appearing on Meet the Press Sunday, National Security Advisor Susan Rice was adamant about limiting Russia's role in Ukraine going forward.

Journalist Simon Shuster said it was “straight out of Hieronymus Bosch.” Writer Philip Gourevitch thought it was more like Bruegel. But the main word to describe the violent clashes in Ukraine’s capital city of Kyiv was “apocalyptic.”

Civil strife often follows a grimly predictable pattern. What at first seems a soluble dispute hardens into conflict, as goals become more radical, bitterness accumulates and the chance to broker a compromise is lost. Such has been the awful trajectory of Ukraine, where protests that began peacefully in November have combusted in grotesque violence.

Expressing alarm at the lethal escalation of political violence in Ukraine, the European Union and the United States scrambled for a quick response Wednesday, threatening punitive sanctions against senior figures in the Ukrainian government. The Obama administration later said it had placed 20 top Ukrainian officials on a visa blacklist.

Three months after the first anti-government protests in Ukraine, the country has experienced its deadliest day of political violence, with nine people dying in clashes between demonstrators and police. The beating heart of the pro-Europe, anti-Russia 'Euromaidan' movement is in Kiev's Independence Square (in Ukrainian, Maidan Nezalezhnosti), and the square is currently in flames after a day of police firing rubber bullets at protesters wielding molotov cocktails and fireworks.

Ukrainian pole vault legend Sergey Bubka on Sunday said the protests rocking Ukraine would not harm its ambitious bid to host the 2022 Winter Olympic Games in the western city of Lviv. Bubka said holding the Winter Olympics in Ukraine would help unite his divided nation.
