An explosion killed seven workers at a warehouse Thursday in the northern city of Burgos, officials said. The blast rocked a warehouse containing equipment and fuel owned by a company building a bicycle lane in Burgos, the Interior Ministry office said. Four other people were seriously injured, Burgos town council member Eduardo Frances told the television station CNN+. Frances said the explosion may have been triggered by a worker handling a container of inflammable liquid. Separately, police and firefighters in Madrid were investigating a powerful explosion Wednesday night at a suburban apartment building that killed two people and injured more than 20, including an infant. The Interior Ministry said Thursday morning that the most likely cause was a gas leak. The president of the Madrid regional government, Esperanza Aguirre, ruled out a terrorist attack. The blast in the Getafe suburb wrecked the facade of the building and forced the evacuation of 44 families.
