Three Ukrainian soldiers have been killed and nine have suffered injuries in the Anti-Terrorist operation (ATO) zone in eastern Ukraine in the past 24 hours, Ukrainian Defense Ministry spokesman Oleksandr Motuzianyk said.

"Regrettably, we have suffered casualties in the hostilities over the past twenty-four hours: three of our servicemen have been killed and another nine have sustained injuries and combat traumas," Motuzianyk said at a press briefing in Kyiv on Tuesday.

The Ukrainian government forces suffered casualties in the Mariupol sector, which saw 28 attacks in the past 24 hours. In particular, Ukrainian military positions near Vodiane were shelled by mortars, cannons, and BM-21 Grad multiple rocket launchers for several hours. In addition, hostiles staged armed provocations in Talakivka, Lebedynske and Shyrokyne, he said.

In the Donetsk sector, the militants continued to shell Ukrainian government forces positions in Luhanske and on the frontline stretch between Kamyanka, Avdiyivka and the Butovka coalmine, using mortars and tanks, Motuzianyk said. Seventeen attacks were observed in the Donetsk sector, including seven employing heavy weapons, he said.

Attacks have also been resumed in the Popasna district in the Luhansk sector, Motuzianyk said, adding that mortars were fired in Troyitske, and gunfire was seen in Stanytsia Luhanska and Triokhizbenka, as well.

The attack mounted near Triokhizbenka damaged a power transmission line, and repairs have begun to resume power supply to the surrounding area. In all, 15 attacks were observed in the Luhansk sector, Motuzianyk said.
