Despite the regime of a full cease-fire was introduced in the midnight of 24 December, pro-Russian militants continued to target Ukrainian servicemen with automatic grenade launchers, heavy machine guns and small arms.
A total of 23 attacks on the positions of Ukrainian servicemen have been registered.
The largest number of attacks was registered in the Mariupol sector near Maryinka, Shyrokyne and Vodyane, the press service of the antiterrorist operation (ATO) said.
There were two shots with 120-mm mortars near Talakivka.
"In the Donetsk sector, our positions were shelled at the Svitlodarsk salient and near Avdiyivka. Zhovte in the Luhansk sector came under fire. Since the fire attacks were purely provocative, Ukrainian servicemen did not open fire," the ATO HQ said in its report.
Earlier, the ATO HQ said that as of the morning of 24 December, silence settled in all along the line of contact in Donbas.
One Ukrainian serviceman was wounded and four were shellshocked on 23 December, the Defence Ministry's spokesman, Andriy Lysenko, said in a daily update the next day.
