Three children were among the victims of the accident, which took place at 9:55 am (local time) on Tuesday, July 16, 2019.
The Mercedes-Benz O309 minibus had reportedly taken a detour and was travelling along an impassable road due to a lack of sufficient documents when its brakes stopped working and it fell into a gorge.
According to the Iranian Red Crescent Society, three of the injured have been transferred with a chopper and six others with ambulances to medical centres in Isfahan.
