Ukrainian defenses around the cities of Severodonetsk and Lysychansk remain under intense pressure from artillery bombardments and air attacks, which have also increased in villages further south, such as Vrubivka.

Russian forces are trying to break through Ukrainian lines in this area and complete the seizure of Luhansk. They control about 90% of the region, according to most estimates.

Serhiy Hayday, head of Luhansk region military administration, said four civilians had been killed in the latest fighting and the nitrogen plant in Severodonetsk had been hit again.

Donetsk region

The General Staff of the Ukrainian armed forces also acknowledged fresh attacks by Russian forces toward Sloviansk in the Donetsk region.

For weeks, Russian forces have been trying to push south to complete the takeover of Donetsk. The General Staff said Russian forces were trying to encircle Ukrainian units around the town of Lyman and were trying to gain full control over the nearby settlement of Drobysheve.
