KIEV, June 12 – President Petro Poroshenko has said that the hybrid war waged by Russia hasn't been successful so Moscow will now attempt to undermine stability in Ukraine from within.

"The hybrid format of the war will be changing in the near future. And after through joint efforts, we have considerably strengthened the national defense, power and efficiency of the armed forces of Ukraine, instead of rushing into a frontal attack, Russia will undermine the stability of Ukraine from within," Poroshenko said at a meeting of the Regional Development Council in Kiev on Friday.
