In particular, the enemy used grenade launchers to shell Ukrainian positions near Popasna (90 km north-west of Luhansk). Small arms and grenade launchers were used by the terrorists to fire at Ukrainian strongholds outside Zaitseve (67km north-north-east of Donetsk). The pro-Russian illegal armed groups also used automatic grenade launchers, heavy machine guns, 82mm and 120mm mortars, prohibited under the Minsk agreements, to shell ATO positions near Avdiyivka (18km north of Donetsk).
