The Ukrainian side quickly reported the incident to the OSCE SMM representatives - via the Joint Centre for Control and Coordination.
One Ukrainian serviceman was wounded in action. They took him to a hospital; his condition is satisfactory.
Over the last 24 hours, Ukraine's combat engineers defused almost six hectares of area and passed 89 explosive items for further safe destruction.
