The OSCE Special Monitoring Mission to Ukraine in its daily spot report on June 15 said its patrol was harassed by warning shots on the part of Donbas militants.
A six-strong SMM patrol on two armored vehicles was monitoring the area in a non-government controlled village of Pikuzy just 23km north-east of the strategic port city of Mariupol, where it stopped to observe fresh tracks from what it assessed to be an infantry fighting vehicle (BMP-type) on the asphalt, according to the report.
