Seven people were killed and 13 injured in an incident involving a bus and a lorry on Emirates Road on Tuesday. A bus carrying 20 people crashed into a lorry carrying rocks that was stationary in the middle of the road near Al Maktoum Airport. Col Saif Al Mazrouei, director of Dubai Police's General Department of Traffic, said: "A truck, which was carrying rocks and can weigh up to 70 tonnes, was stopped on the third lane from the right because it initially crashed into a pick-up truck. "The bus driver, who died in the incident, [must have been] surprised to see the truck in the middle of road and crashed into it." Lt Col Ahmad Burqibah, deputy director of Dubai Police's Search and Rescue Department, said that many of the bus passengers were trapped in their seats. "Rescue units used hydraulic tools and shears to cut through the vehicle and extract bodies and those who were injured," he said. Dubai Police chief Lt Gen Khamis Al Muzeina urged motorists to stop in a safe place if involved in a traffic incident. "People must be very careful while driving and not take the risk of driving while exhausted," he said. "It is important to stop in a safe zone in case of an accident, to avoid another one." The chief said that bus drivers should take extra care, abide by speed limits and keep safe distances between vehicles, as they carry large groups of people. The incident took place at 8am on Tuesday and the injured were taken to hospital.
