DAMMAM — Three students from a middle school for girls sustained moderate injuries when their minibus overturned after colliding with another vehicle. There were nine students in the bus and all were going to take their examinations when the accident took place, said Red Crescent spokesman Fahd Al-Ghamdi. The force of the collision was so hard that the driver lost control and the vehicle tipped over, injuring the three students. The others were unscathed. Traffic officers are investigating the causes of the accident.
