Last night, Ukraine's President Viktor Yanukovych, working with opposition leaders in the months-long protest, declared a truce, hoping to begin negotiations. Within hours, each side was accusing the other of betraying the agreement, and some of the most-violent clashes to date took place, leaving dozens of protesters lying dead in Kiev's Independence Square, and hundreds more injured in nearby aid centers and hospitals. With the failure of these negotiations, and the escalating violence, fears are growing that President Yanukovych will declare a state of emergency, bringing military enforcement into the situation.
