KIEV, July 25 - A number of nationalist groups, including the National Corps, Svoboda and Right Sector, plan in September to begin actions blocking the activities of Russian companies in Ukraine, parliamentary lawmaker Andriy Illenko said.

"We will begin implementing the bulk of this action in September. And we are calling on all Ukrainians to finish this disgrace together. If the authorities do not want to do this, civil society should take everything in their hands," he said.
