Thirteen fire crews and eleven SEM ambulances attended the scene. Despite their efforts, medical teams were unable to save the five young victims found inside. Five other residents suffered minor injuries. Catalan President Salvador Illa expressed his shock and offered condolences to the families and the town of Manlleu.
