At least two workers have been killed and several injured after a bridge under construction collapsed in Andorra.
Four workers are still reportedly buried and a desperate rescue operation is underway to try to dig them out. The exact reason why the bridge fell is still not known but a weakness in a concrete pillar, causing the rest of the structure to crack, is thought to be a possibility. Officials say several Portuguese nationals were among the team working on the Dos Valires tunnel near to the construction site at the time. Work on the tunnel, linking the Andorran towns of Encamp and La Massana, is scheduled to finish next year.
