– Red vigilance in Gironde –

In the Bouches-Rhône, about twenty kilometers from Marseille, a fire which broke out at the end of the afternoon near Pennes-Mirabeau, covered 35 hectares, according to the Departmental Fire and Rescue Service ( Sdis). Some 200 houses threatened by the flames have been protected.

«A thick plume of smoke was visible above the A7 motorway», which was cut, noted an AFP journalist. A traffic jam formed on the detour route on this day back from vacation.

«We have been stuck for an hour» around Pennes-Mirabeau, said a Marseille vacationer, Jean-Baptiste Mouttet, who is struggling to return home.

Planes dropped retardant in the hills and the scrubland to prevent the spread of the fire while many fire trucks went to the area.

France has already been hit by several large fires since the beginning of the summer. Nearly 21,000 hectares were ravaged in Gironde while 1,600 hectares burned in a fire in Provence, south of Avignon, in mid-July.

The Gironde department will once again be placed on red alert for the risk of fires in the forest, the prefecture announced on Sunday.

In the Hérault department, a fire which broke out on Tuesday about twenty kilometers from Montpellier destroyed 800 hectares of vegetation while 1,200 hectares were destroyed in Ardèche the same week.

If summers are dry in the South, with global warming, the intensity of these episodes of drought is likely to increase further, according to UN climate experts.

In France, with global warming, «the activity (of the fires) will intensify in the areas where it is already strong, in the South-East», underlined Jean-Luc Dupuy, expert at the National Institute of research for agriculture, food and the environment (Inrae) at the end of June.
