On May 30, an SMM patrol consisting of six members and two armored vehicles arrived at the SMM camera site just outside the disengagement area near Petrivske 41km south of a militant stronghold of Donetsk.
"At 10:58 the patrol members were stationary in two vehicles with the doors open when they all heard a whistling sound followed by an explosion, and saw dark grey smoke coming from behind an abandoned brick farm building, 200-300m south-south-west, assessed as outside the disengagement area," reads the OSCE SMM's daily spot report.
