Protesters erected barricades from charred vehicles in central Kiev as the sound of stun grenades pierce the freezing air, after a night of rioting sparked by passage of laws aims at curbing street protests.

Dozens of protesters remain camped out on a central street in Kiev on Monday, as some vehicles torched by protesters overnight continue to blaze.

A large demonstration against anti-protest laws turned violent Sunday, when hundreds of radical protesters broke off from the main peaceful rally and marched toward the parliament building. They began attacking rows of police with sticks, stones and fire bombs, setting police vehicles on fire. Police responded with tear gas and water cannons. Dozens of protesters and police were injured.

The government is set to hold talks with leaders of the opposition Monday.
