Twelve people died and 23 were injured Friday in a mountainous area of the northern Mexican state of Durango when the bus they were travelling in rolled down a ravine, according to dpa. The bus was apparently speeding as it turned a bend and fell 100metres into a ravine, the state undersecretary for civil protection, Jorge Paniagua, told dpa. The accident occurred in an area known as The Devil's Spine, in the town of El Salto, about 1,000 kilometres north-west of Mexico City. The victims, most of them elderly, belonged to a Christian group from Tlaxcala that was on a pilgrimage.
