"The enemy shelling of our positions in the Donetsk and Mariupol sectors intensified sharply. Sporadic use of heavy weapons, including mortars and infantry fighting vehicles, was recorded," he said.
"A significant part of the shelling was aimed, that's why ATO forces returned fire," the spokesman said.
In addition, according to Lysenko, "there is a lull in the Luhansk sector, however, in the Donetsk sector, the enemy violated the "ceasefire" on all fronts."
"On Thursday, the largest number of enemy attacks was recorded near the Donetsk airport, in particular, in the village of Pisky," he said.
