Observers of the OSCE Special Monitoring Mission (SMM) have registered the usage of 'Grad' multiple rocket launchers in Donbas for the first time since the second Minsk agreements were made in February, Deputy Chief Monitor of the mission Alexander Hug has said.

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 second Minsk agreements in the middle of February, he said at a briefing in Kyiv on Thursday.

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.
