"Together with our partners, we are not only looking for new international mechanisms for resolving existing challenges, but we also are preparing to react absolutely adequately to them. The best way to stop the aggressor is to be ready for a worthy defense and to repel any attack," Poroshenko said.

He recalls that three Ukrainian servicemen were killed over the past day, and armed provocations and shelling using weapons that should have been withdrawn for a long time do not stop despite the agreements reached on the ceasefire regime.
