At least eight South African children were killed on Wednesday when a minibus carrying them to school drove through a barrier at a railroad crossing and was rammed by a train, officials said. The five other children in the vehicle and the driver were all critically injured and were taken to hospital near the crash site in Blackheath, about 25 kms (15 miles) east of Cape Town. "The crossing is protected by road signs, flashing lights and booms, which were confirmed to be in working order," the Railway Safety Regulator said in a statement quoted by Reuters. No on was injured on the train.
