The Security Service of Ukraine has said it is well-informed on the plans of the Communists to organize provocations on May 1-2, SBU chief advisor Markiyan Lubkivsky said.

"SBU is well-informed on the plans of the Communists to stage disorders on May 1-2. We won't admit provocations of separatists and communists gang," he said at a briefing on Thursday.

He mentioned Lviv, where Communists attend sport clubs to hire Ukrainian sportsmen for working at rallies in this city.

"We have also uncovered attempts to encourage young people to take part in these destabilizing actions in Kyiv, Chernihiv and Vinnytsia," he added.
