"The enemy is using multiple launch rocket systems with thermobaric ammunition in Chasiv Yar," a spokesman said.
"This type of ammunition destroys and burns everything in its path."
The Armed Forces noted that the Russians are trying to leave Ukrainian defenders with nowhere to hide and defend themselves.
"They destroy everything left after strikes by their aviation," the spokesman said.
Voloshyn added that the enemy constantly attacks the Chasiv Yar sector and keeps trying to advance there.
In the last week alone, the Russian army conducted 8,350 strikes at the positions of Ukrainian defenders in this area using various types of weapons.
The spokesman added that the Armed Forces control Chasiv Yar, use all types of weapons against the Russians, and do not allow Russian troops to enter the city.
