Anti-government protestors in Ukraine toppled a landmark statue of former Soviet leader Vladimir Lenin in central Kiev on Sunday.
Video filmed by an opposition supporter showed protestors pulling down the statue using a rope and cheering after it fell.
Sunday's demonstration was the largest rally Ukraine had seen since the 2004 pro-democracy Orange Revolution.
Hundreds of thousands of Ukrainians flooded the capital city of Kiev to demand the ouster of President Viktor Yanukovych after he ditched ties with the European Union in favor of Russia and police launched a crackdown on earlier demonstrations.
The government announced an investigation of opposition leaders for an alleged attempt to seize power and warned that demonstrators could face criminal charges.
On Monday, Ukrainian officials said anti-government protestors had begun evacuating a government building they had been occupying for days as buses carrying government troops started to move towards Kiev.
