Ukraine's acting President Oleksander Turchynov says Russia "is at war" with his country, and that local and institutional support for Moscow is a "colossal problem" in eastern Ukraine, RFE/RL reports.
Speaking on May 4 with Ukraine's Channel 5 TV, Turchynov accused Moscow of trying "to destabilize the situation completely" in eastern and southern Ukraine.
He said Odesa is "one of the Russian Federation's main targets."
But he said "patriotic" Ukrainians had blocked the efforts of "local provocateurs and separatists" whom he accuses of "organizing" violence in an attempt to bring the Odesa "to its knees."
Turchynov also said pro-Russian "organizers and perpetrators" of violence in Odesa during the weekend included "a lot of people with Russian passports and guest stars" from Moldova’s breakaway region of Transdniester.
To recall, dozens were killed in fire at the trade union building in Odessa amid clashes between separatists and pro-Ukrainian activists.
