The number of children killed when the bus they were travelling in caught fire in northern Colombia rose to 33 Monday, after another child died from severe burns. The accident happened Sunday near the town of Fundacion, in the Caribbean province of Magdalena. The bus was carrying 43 people, most of them children. The bus driver, 56, turned himself in to the authorities Monday. He had no driver's license, and the bus had no insurance, dpa reported. There was speculation over whether the fire might have been caused or made worse by a shipment of contraband fuel loaded onto the bus.
