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.
