Mobilizing after midnight, thousands of riot police officers and Interior Ministry troops broke through barricades around Independence Square, pushed demonstrators back and formed tight cordons around them. They then called in bulldozers and other heavy equipment to raze some of the protesters’ tents and barricades.
The security forces clashed with protesters and briefly tried to regain control of City Hall.

The retreat let protesters reclaim the square and they quickly rebuilt their barriers, this time using heaping bags of snow.
