Ukrainian officials have warned that Russia is conducting offensive operations along much of the frontline, with Ukraine’s military trying to hold its positions as its ammunition begins to run low and United States funding remains stalled in Congress.

Fighting is intense in the northeast along a stretch of territory where the regions of Kharkiv and Luhansk meet. Ukraine announced earlier this week it had withdrawn its forces from the Kharkiv village of Krokhmalne in order to take up more advantageous defensive positions on higher ground, while reports suggest Russian forces have continued to press in the area.

The General Staff of Ukraine’s army said Ukrainian forces had faced down 13 attacks nearby Krokhmalne, on Tabaiivka to the northwest of the village and on Stelmakhivka to the south.

“The enemy is focusing on a large number of artillery attacks, trying to advance,” a spokesperson for Land Forces Command told Ukrainian television about the situation near Krokhmalne.
