Full Disclaimer SUSANA VERA/Reuters A powerful gas explosion tore through a residential building in central Madrid on Wednesday, killing at least three people and ripping the facade off the structure. A tower of smoke rose from the building, where repairs were being done to a gas boiler, and billowed through Toledo Street, near the city’s centre. Aerial footage shared by Spain’s National Police showed rubble covering a nearby schoolyard – though Madrid’s mayor said no one was seriously injured at the school.
