France has been suffering its largest wildfire in at least 50 years, according to disaster officials.

Firefighters in southern France have warned that a huge fire they have been battling, which spread across an area bigger than Paris, could reignite as the region continues to face a scorching heatwave.

Authorities on Sunday said hot, dry winds and a heatwave would make the work of firefighters even more hazardous.

The fire has ravaged a vast area of France’s southern Aude area, larger than the size of the nation’s capital, killing one person and injuring several.

“It’s a challenging day, given that we are likely to be on red alert for heatwave from 4:00pm (14:00 GMT), which will not make things any easier,” said Christian Pouget, Aude’s prefect.
