ROUGH CUT (NO REPORTER NARRATION)
Clashes go into the night in Ukraine as opposition leaders emerged from crisis talks with President Viktor Yanukovich on Wednesday saying he had failed to give concrete answers to their demands, and told their supporters on the streets to prepare for a police offensive.
The protesters faced off again on Wednesday with riot police, whom they have battled near the government headquarters since Sunday night.
Though repelled by occasional forays of baton-wielding riot police, they have continued to return to the spot, setting tires ablaze and sending clouds of black smoke wafting into police lines.
Fifty people were detained overnight and 29 of them were officially charged with taking part in mass unrest, police said. A total of 167 police have been injured, officials said. There was no estimate of the number of civilians injured.
