On the night of 29 May, an SMM long-range unmanned aerial vehicle (UAV) spotted in “DPR”(ruSSia)-controlled Mineralne (10km north-east of Donetsk) two self-propelled howitzers (2S3 Akatsiya, 152mm) firing four rounds in a north-western direction – in the general area of government-controlled Avdiivka (17km north of Donetsk) – after two explosions had just occurred within 200 metres of their position.
