President of Ukraine Petro Poroshenko says Joint Forces Commander Serhiy Nayev will be primarily responsible for repelling any large-scale armed aggression in case Russia goes for a full-blown offensive in Donbas.

Speaking at a meeting with chiefs of security agencies on Monday on the day when the Anti-Terrorist Operation is changing its format to become a Joint Forces Operation, Poroshenko gave a number of instructions in this regard, according to the presidential administration press service.

"In the event of an aggravation of the situation, we must involve additional forces and means of the Armed Forces of Ukraine, all other units without exception, other components of the defense and security sector," Petro Poroshenko said.

"I want to emphasize separately that the completion of the regime of a large-scale antiterrorist operation does not deprive us of the possibility of announcing the ATO at any time when there is a terrorist threat in the liberated territories," Petro Poroshenko noted.

The President stressed the importance of closely monitoring the situation and counteracting the risks and threats, including the activities of sabotage groups.
