KIEV — In a striking concession aimed at defusing the civil uprising that has gripped Ukraine, President Viktor Yanukovych on Saturday offered to install opposition leaders in top posts in a reshaped government, proposing one of them, Arseniy P. Yatsenyuk, as prime minister and another, the former boxing champion Vitali Klitschko, as vice prime minister for humanitarian affairs.
Yatsenyuk, who seemed confident that the opposition had pushed the president to the brink of defeat, rebuffed his offer.
“No deal,” Yatsenyuk wrote on his Twitter account, addressing Yanukovych. “We’re finishing what we started. The people decide our leaders, not you.” Full story for BostonGlobe.com subscribers.
