"Maidan is moving to Lviv and Kharkov. People are shouting: 'Revolution! Death to the criminal regime!' The revolution has a beginning but has no end," Pushkov wrote on his Twitter page.
Earlier it was reported that protests have been underway since Saturday near the presidential office building in Kiev. Activists are demanding resignation of country’s Interior Minister Arsen Avakov and commanding police officers in the Zakarpattia Region.
It was also reported that protests sparked on Sunday in Dnepropetrovsk, Lviv, Kharkov and Cherkassy.
Right Sector members have been protesting near the regional administration building in Lviv. They brought tires and tents with them. In Kharkov, it has staged a protest near the regional administration.
"I have persistently been told in Europe that Ukraine is almost free of far-right radicals and democratic. They should go to Mukachevo to see the democracy," the lawmaker wrote on Twitter.
The western Ukrainian town of Mukachevo became one the country’s trouble spots on Saturday after Right Sector members exchanged fire with local police. According to different reports, between one to three people were killed and 11 were injured.
The Right Sector was formed as a coalition of nationalist and neo-Nazi organizations during the Maidan protests in Kiev at the end of 2013. It has played a major role in violent clashes with police, and played a key role in escalating last year's violence in Kiev which culminated in the February 2014 coup. In November 2014, Russia’s Supreme Court blacklisted Right Sector as an extremist organization and banned its activity in Russia. Earlier, Russia launched a criminal case against leader Dmitry Yarosh for public incitement of terrorism.
