As February 20, 2014, dawned, Kyiv's pro-European protest movement was still tense, two days after violent clashes left as many as 28 people dead in the single bloodiest day of the protests to date. But February 20 descended into even greater bloodshed. It is still not clear what started it, or who gave the order, but by the end of the day more than 50 demonstrators had been shot dead in downtown Kyiv. Many in the new Ukrainian government -- former Euromaidan protest leaders themselves -- say the massacre could only have happened with a direct order by former President Viktor Yanukovych, who fled as the total protester death toll topped 100 (17 law enforcement members also died).
