"The armed forces of the Russian Federation and their mercenaries violated the ceasefire four times on January 4. Two Ukrainian soldiers were injured in a booby-trap blast," the press center of the Joint Forces Operation Headquarters said on Facebook in a morning update on January 5.

The enemy opened fire from grenade launchers of various types, heavy machine guns, and small arms.

Under attack came Ukrainian positions near the town of Avdiyivka, and the villages of Verkhniotoretske, Vodiane, and Novoluhanske.

Since Sunday midnight, Russia-led forces have been observing the ceasefire.
