Firefighters in southwestern France were working to control the last hot spots of a massive wildfire that has burned an area four times the size of Paris and forced thousands out of their homes. The blazes that have burned 42,000 hectares of pine forest and touristic areas in Bordeaux’s Gironde region haven’t spread for several days, and officials are cautiously optimistic. But for those on the frontline, the danger hasn’t eased. Officials say more than 230 firefighters have been injured, and the toll keeps rising the longer they stay on the line.
