"This afternoon, militants received an order to attack Avdiivka industrial area in the evening, and to be more precise, to take control of the Yasynuvata junction and surrounding territory.
"We thought it was another fake, but the situation worsened in the evening. They started to bring up hardware and manpower from Yasynuvata, with firing points in Makiivka having become active.
"At this stage, the attack is underway as terrorists attempt to take control of the industrial area in Avdiivka. They employ 120-mm and 82-mm mortars, heavy machine guns, and grenade launchers," he wrote.
