More forest fires broke out in southern France after firefighters had fought for 24 hours to control earlier blazes that raged across vast tracts of woodland killing four tourists. Local authorities suspect arsonists of being behind some 30 devastating blazes that started late and shrouded the picturesque Provencal countryside in thick smoke, forcing thousands of holidaymakers to flee villas and camp sites. Most of those fires were under control officials said, but a handful of new fires, fanned by gusts of powerful wind, were threatening new areas of forest.
