"SMM registers a couple of hundreds of shellings every day. Particularly, on May 2, fire from 'Grads' was heard in Donetsk. It caused casualties among civilians. OSCE notes that it was the first time they heard 'Grads' fire since the adoption of the latest Minsk agreements in the middle of February," he said.
"In fact, the mission observes heavy weaponry in the confrontation region every day," Hug said.
Hug also said that the town of Hranitne controlled by Ukrainian troops was shelled from 'Grads' at the end of April.
