The incident occurred in the heart of Madrid when part of a building that was being renovated caved in, causing panic and chaos. Mayor Jose Luis Martinez-Almeida reported that all four victims included a 30-year-old Spanish woman overseeing the project and three male workers from Mali, Guinea, and Ecuador, aged between 30 and 50. Rescue teams utilized drones and sniffer dogs to locate any missing persons, leading to the recovery of the last victims the following morning. Meanwhile, three others sustained injuries amid the chaos. Witnesses noted that the façade remained intact despite the substantial internal damage. The structure was earmarked for transformation into a four-star hotel, and an investigation into its collapse has commenced as the city mourns this heartbreaking loss.
