The Sol metro station in Madrid was temporarily closed by the Community of Madrid due to unsanitary conditions. Reports indicated high concentrations of ammonia in ventilation shafts, which officials attributed to a housing protest encampment in the Puerta del Sol area. While the regional government cited biological risks, labor unions denied requesting the closure, and the Transport Minister criticized the decision as harmful to commuters.

Following intensive cleaning and disinfection, the station reopened after laboratory tests and documentary analysis confirmed that all required safety and health standards had been restored.
