Since huge demonstrations broke out this month, barricades have sprung up around Kiev as Ukrainians call for the resignation of President Viktor Yanukovych.
Since December 1, the protesters have been living in tents around the barricades, with temperatures dropping as low as -13C (8F).
Protesters have been protecting their territory by pouring water in front of the barricades to make the ground slippery.
Some of the barricades by the presidential administration and cabinet building were dismantled on Monday.
Stronger barricades went up around Maidan, made from sandbags, tires, wood, barbed wire and snow.
The EU's top foreign policy advisor, Catherine Ashton, was in Ukraine when the brawl occurred and expressed disgust at how the protesters were treated.
Despite the brawl and damage done to the barricades, the EuroMaidan participants have simply started rebuilding.
