"More effort will have to be made to maintain the situation in the region on the eve of the anniversary of the events that occurred on May 2 last year in Odesa. We understand that pro-Russian forces want to use this anniversary to destabilize the situation in the city with a single goal - to create another "republic." We assure you and let everyone hear it - they will not succeed!" Vovk said.
He noted that the SBU has developed an action plan to ensure the safety, especially on the eve of and on May 2 itself.
"We have to be prepared for anything, and we have sent groups to numerous cities to study the situation, monitor and prevent preparations to commit any acts against life and health of citizens," Vovk said.
He expressed confidence that the Security Service and other law enforcement agencies will be able to stand up to all possible challenges.
Earlier, Prime Minister Arsenii Yatseniuk said that Russia's direct military intervention into Ukraine from Russia during the May holidays was a pissibility.
