Some 20,000 protesters march to the parliament building in Kyiv to demand a vote on a series of reforms aimed at defusing the crisis by curtailing President Viktor Yanukovych's powers. Clashes quickly erupt, with some protesters hurling stones and torching three police trucks while police fire rubber bullets and smoke bombs.
Antigovernment protesters seize the Kyiv office of Yanukovych's Party of Regions, reportedly scaling the facade and entering through the first floor. They throw documents out of the windows. Later, part of the building catches fire as protesters outside continue to throw Molotov cocktails.
