KIEV, Ukraine - A top Ukrainian opposition leader on Thursday urged protesters to maintain a shaky truce with police after at least two demonstrators were killed in clashes this week, but some in the crowd appeared defiant, jeering and chanting "revolution" and "shame."
Emerging from hours-long talks with President Viktor Yanukovych, opposition leader Oleh Tyahnybok asked demonstrators in Kiev for several more days of a truce, saying the president has agreed to ensure the release of dozens of detained protesters and stop further detentions.
But other opposition leaders offered mixed reports on the outcome of the meeting, with Vitali Klitschko saying negotiations had achieved little.

Thick black smoke from burning tires engulfed parts of downtown Kiev as an ultimatum issued by the opposition to the president to call early election or face street rage was set to expire with no sign of a compromise on Thursday.
He and Tyanhnybok were booed at the barricades by angry demonstrators and the atmosphere appeared tense.
"We are not going to sit and wait for nobody-knows-what," said Andriy Pilkevich, a ski mask-wearing protester who was building barricades near police lines from giant bags of ice. "Those who want to win must fight."
Interior Minister Vitali Zakharchenko issued a statement guaranteeing that police would not take action against the large protest camp on Independence Square, known as the Maidan. He also called on the police to exercise calm and not react to provocations.
The developments came as hundreds of enraged protesters in several regions in western Ukraine, where Yanukovych has little support, seized government offices and forced one governor loyal to Yanukovych to resign.
At least two people were killed by gunfire Wednesday at the site of clashes in Kiev. Demonstrators had pelted riot police with barrages of stones and set police buses on fire, while the officers responded with rubber bullets, tear gas and stun grenades.
Opposition leaders had set a Thursday evening deadline for the government to make concessions or face renewed clashes. Protesters had quenched barricades that had been set on fire, but lit them again during the evening.
Although one opposition leader, Arseniy Yatsenyuk, said after the talks that "there is a really good chance" of stopping the bloodshed, Klitschko was more downbeat.
"The only thing we were able to achieve was not much," a grim Klitschko told the crowd.
