===U.S. Ambassador to Ukraine Geoffrey Pyatt told CNN on Thursday that "extremes on both sides are gathering strength" because of the instability. Even then, Pyatt said, "It's very clear that, for the United States, the preponderance of the responsibility rests with the President Yanukovych."

"Our position is (that) President Yanukovych needs to lead his country into a new future, and he needs to do so through the vehicle of a new government, change to the constitution and the political order."===
