Since the beginning of the week, the Russian army has increased the number of attacks in the Kharkiv sector, particularly in the area of Vovchansk. Russians are concentrating forces and equipment there.
This was reported by the Kharkiv Operational Group.
Over the past day, 517 attacks on the positions of Ukrainian defenders took place.
"The enemy is using artillery, mortars and multiple rocket launchers to attack the positions of the Ukrainian Defence Forces, which may indicate the enemy's intention to launch active assault operations," the Defence Forces said.
The intensity of shelling remains particularly high in the area of Vovchansk.
"According to intelligence, the Russian occupation forces are increasing their military presence, conducting preparatory activities, concentrating forces and equipment in the area. The intensification of shelling in the Kharkiv sector by the Russian occupiers is a serious challenge that requires due attention," the Kharkiv Operational Territorial Group added.
