Some 1,300 firefighters were drafted in to stop the blaze from flaring up amid fears that winds blowing around 50 kilometres per hour could fan lingering hot spots. The blaze – the largest in at least 50 years – tore through 16,000 hectares of vegetation, disaster officials said.
Temperatures in the coming days are expected to hit 42C in some areas, according to national weather service Meteo France.
