"Between 10:30 p.m. on June 2 and 5:30 a.m. on June 3, the SMM-positioned in the "DPR"-controlled Tekstilshchik area of Donetsk city (14 km east-north-east of Marinka) made a number of observations.
"It observed, inter alia, eight tracked armored vehicles moving west, four of which were main battle tanks (MBT) at 10:30 p.m.; four MBTs at 11:03 p.m.; a military-type truck moving west, towing a 122-mm artillery piece at 11:45 p.m.; two T-64 MBTs moving west at 4:30 a.m.; and a column of one infantry fighting vehicle (BMP-2), three military trucks (one carrying an ZU-23-2 anti-aircraft gun), and two T-72 MBTs, moving west, at 4:50 a.m. In addition, the SMM - at the same location - heard approximately 100 outgoing artillery rounds fired from a location 1-5km north-north-west of its position between 4:30 and 04:40 a.m.; an outgoing salvo of BM-21 multiple launch rocket system (MLRS) Grad rockets fired from a location 1-5 km west of its position at 4:55 a.m.; and, 100 outgoing artillery rounds fired from a location 5 km north-north-west of its position.
"Between 4:30 and 5 a.m., the SMM - positioned in Donetsk city-centre - heard several salvos of outgoing MLRS rockets and approximately 100 incoming heavy-artillery rounds.
"Between 7 and 8 a.m, the SMM - mobile in an area 6-9 km east of Marinka - observed seven T-64 MBTs facing west. In addition, it heard, on two separate occasions, more than five salvos of outgoing MLRS (BM-21) rockets and heavy-mortar rounds; and 12 outgoing MLRS Grad rockets and mortars.
"At approximately 6 a.m., an SMM unmanned aerial vehicle (UAV) observed intense shelling targeting an intersection of the H15 highway 3.5 km south-west of Marinka. The UAV spotted four 2S3 Akatsiya 152-mm self-propelled howitzers 9 km south-west of the town at 3:30 p.m.
"The SMM made several attempts between 10:45 a.m. and 12:11 p.m. to contact high-ranking "DPR" personnel - including the "DPR" "prime minister", "parliamentary speaker", "minister of defense" and "chief of the general staff" - in order to facilitate a cessation to the fighting around Marinka. Either they were unavailable or did not wish to speak to the SMM.
"At 3 p.m. the SMM received a letter from the Ukrainian Ministry of Defence, saying Ukrainian Armed Forces heavy weapons would be placed on the contact line in order to deal with the "real threat" posed by the fighting in Marinka, which they said had started at 6 a.m. that morning. Ukrainian officials later publicly acknowledged that the weapons had been used, saying their use was necessary in thwarting a "DPR" attack.
"The Representative of the Russian Federation Armed Forces to the Joint Centre for Control and Co-ordination told the SMM at 3 p.m. that a cease-fire around Marinka would take effect at 5 p.m.He told the SMM at 9 p.m. that the situation around Marinka was currently calm. At around 7 p.m. a representative of the Anti-Terrorist Operation command in Kramatorsk and the "DPR" "ministry of defense" confirmed to the SMM that Marinka was under government control," the reports reads.
