Ukraine Riot Police, Interior Troops Clash With Protesters

A day after the government promised not to use force against protesters

Ukrainian riot police used force in an attempt to disperse protesters in downtown Kiev early Wednesday, further stoking opposition leaders, who vowed to coax hundreds of thousands into the streets, rejected more negotiations and demanded President Viktor Yanukovich's resignation.

"There can be no compromises with thugs and dictators," Vitali Klitschko, a world heavy weight boxing champion and an opposition leader said in a statement published Wednesday on his party's official website. "Today question number one is unquestionably the resignation of Yanukovich and his entire rotten administration."
