Novosti Donbassa reports that separatist fighters have accidentally set fire to their own Grad rocket launcher and destroyed the depot of a vegetable company by mistake in the Donetsk town of Dobropol.

A comment on a local VKontakte group read (translated by The Interpreter):

"From this area they fired several volleys from both installations towards the town of Dobropol. While firing a salvo, one of the launchers caught fire. Not all the ammunition was fired. Out of the 40 rockets, 14 remain unused, and one of them malfunctioned and fell on a barn near the launch site. They allegedly fired at a Ukrainian checkpoint which is on the outskirts of the town, towards Svyatogorsk. But a mistake was made in the firing adjustments and all of the missiles fell on the Perspektivy vegetable depot, where a woman who worked for the company was seriously injured. Two rockets fell on a neighbouring premises, where a young man who was working as security guard died."

The Novosti Donbassa report says the area is now cordoned off by the Ukrainian military as the separatists had placed mines around the burnt launcher.
