After nearly two months of ignoring mass demonstrations calling for his ouster, Yanukovych offered to meet some of their demands, after crowds angered by the deaths of at least two protesters and allegations of abuse by authorities besieged government buildings in scores of cities in western Ukraine.
At a meeting today with religious leaders, Yanukovych vowed that, at a special parliament meeting on Tuesday, he would push through changes to his Cabinet, grant amnesty to dozens of jailed activists and amend harsh anti-protest legislation.
"Just a month ago, the Maidan would have gone home," Klitschko told reporters tonight, according to the Interfax news agency. "Today, people are demanding the president's resignation."
The protest law enacted last week appeared to have backfired on Yanukovych, sparking confrontations in which demonstrators threw stones and firebombs at police, who responded with tear gas and rubber bullets.
The violence since Sunday was a harsh contrast to the determined peacefulness of the anti-government protests that have gripped the country for the last two months.
At least two demonstrators were killed this week in clashes with police and protesters have seized government offices in cities in western Ukraine, where support for Yanukovych is thin.
In a separate incident, a protester was found dead outside Kiev this week after going missing from a hospital together with a prominent activist who was beaten but survived.
