Hundreds of Ukrainian right-wingers are rallying in Kiev to protest government policies.

The radical Right Sector group was one of the most militant factions in the massive protests in Ukraine's capital that prompted pro-Russia President Viktor Yanukovych to flee the country in February 2014. Since war broke out in eastern Ukraine between government forces and pro-Russia separatists several months later, the Right Sector has fought on the government side.

Right Sector militants, however, keep running into disputes with local Ukrainian authorities. The activists claim they are trying to clamp down on corruption and nepotism but Ukrainian authorities accuse Right Sector of using violence to reach its goals.

Speaking Tuesday at the national Right Sector conference, group leader Dmytro Yarosh called for a referendum to impeach President Petro Poroshenko's government.
