"Moreover, we have established not only perpetrators but also masterminds. The investigations are underway. The results will be published later," the press service of the Kharkiv Regional State Administration quoted Ihor Rainin's statement made on Wednesday.
He also praised the efficiency of the actions of the Security Service of Ukraine and the highest level of coordination among all law enforcement agencies in the region.
Speaking about the next elections to the local councils, Ihor Rainin promised to make every effort to ensure their fairness.
"It is natural that any political process and political struggle is related to a certain charged environment. I will do my best as the head of the regional state administration to ensure that the elections are fair. The only thing needed is that the Verkhovna Rada of Ukraine makes decisions on the electoral legislation and the date of the elections," Rainin said.
