The fire service says the suspected cause of yesterday's fire in Monmouth is believed to be accidental ignition.
Over 40 crews from Fire and Rescue Stations across South Wales attended the blaze at the Peacocks store on Monnow Street.
Crews worked tirelessly to manage and contain the fire, preventing it from spreading to neighbouring properties.
The premises smouldered overnight, and crews continued to dampen down hotspots, securing the area and protecting the community from further risk.
South Wales Fire and Rescue Service remained at the scene while a fire investigation was conducted. The suspected cause of the fire was determined to be an accidental ignition.
The road was closed as a safety precaution and those needing to travel along Monnow Street were advised to plan alternative routes or transportation methods. The road has since been reopened.
The property has now been boarded up and secured as a safety precaution.
