Ukrainian Joint Forces Commander, General Volodymyr Kravchenko has said Russian-led forces have already violated the newly-agreed truce in Donbas.

"The situation along the contact line is stable and under control. Unfortunately, at 00:20-00:45 Kyiv time, the enemy shelled a unit of the 36th separate marine infantry brigade, using riles, hand-held anti-tank grenade launchers, and heavy machine guns. The Joint Forces had no casualties. Our units did not fire back. The shelling that took place at night caused no harm to the life and health of the personnel," he said at a briefing in Donetsk region, according to an UNIAN correspondent.

In addition, according to Kravchenko, at about 09:00 Kyiv time, the invaders opened fire from hand-held anti-tank grenade launchers three times in the zone of responsibility of the 79th separate airborne assault brigade.

As UNIAN reported earlier, participants in the Trilateral Contact Group (Ukraine, Russia, OSCE) on the peace settlement in Donbas on July 22 agreed on a complete and comprehensive ceasefire on the contact line from 00:01 on Monday, July 27.

The new ceasefire regime began to operate in Donbas at 00:01 Kyiv time on July 27.

Before the new agreements came into force, President Volodymyr Zelensky had a phone call with his Russian counterpart Vladimir Putin.

Senior military officers and President Zelensky say the new truce does not mean that the Ukrainian military will not be able to return fire in response to enemy attacks.
