During May 23, massive shellings were observed on the stretch from Shumy, Mayorske to Avdiivka. The enemy used small arms and AGS-17 “Plamya” and Z-23-2 automatic grenade launchers (mounted to mobile vehicles) by its firing groups. Insurgents inflicted a firestrike from 120-mm mortars on the advanced positions of Ukrainain troops in the vicinity of Troitske.

In the Artemivsk direction, the positions of Ukrainian troops were shelled from 122-mm cannon artillery and mortars (82- and 120-mm) near Luhanske, Myronivske,Sanzharivka and Rozsadky.

South of Donetsk (in the vicinity of Starohnativka and Hraninte), the positions of Ukrainian troops were repeatedly fired at from AGS-17 and large-caliber machine guns (the enemy tried to provoke retaliatory fire to determine the firing system of the ATO forces in order to coordinate the further actions of their sabotage and reconnaissance groups). Insurgents opened fire from 120-mm mortarts several times in the area.

In the vicinity of Krymske, Sokilnyky, Shchastya, Stanytsia Luhanska, insu rgents have repeatedly opened fire from 82-mm mortars and AGS-17, firing at the advanced positions of the ATO forces. On the ZhovteVesela Hora stretch, insurgents have pushed forward a battery of 82-mm mortars and at least three AGS-17 “Plamya” (in the direction of a river between Raivka and Zhovte). Terrorists opened “sighting” fire.

In the area between Leninske and Nelipivka, a terrorist sabotage and reconnaissance group (12 people) has attempted to penetrate deep into the battle formations of Ukrainian troops under cover of heavy mortar fire, practically bypassing Artemove and Shumyfrom the southwest. The group’s goal was to uncover the defense system in the vicinity of Artemove and possibly reach the outskirts of Dzerzhynsk. However, when they reached the Zalizna Creek, the insurgent saboteurs were found by the outposts of the ATO forces and as a result of a firefight were forced to retreat (at least two subversives were wounded).

In the seaside (Mariupol) direction, insurgents fired with large-caliber machine guns and automatic grenade launchers in the vicinity of Shyrokyne on Saturday, May 23.
