Protesters surround the International Convention Center in Kiev, Ukraine and throw objects and fireworks into the building, also known as "Ukrainian House."

Police reportedly were in position inside.

Broken windows were visible along one side of the building

Hundreds of activists have already occupied City Hall and the agricultural ministry, both close to the energy ministry building, in increasingly violent protests against Yanukovich's rule.

The rallies against Yanukovich erupted last November after he pulled out of a free trade deal with the European Union in favor of closer economic ties with Russia. They have since spiraled into protests against misrule and corruption.
