French authorities ordered 4,000 more people evacuated from tourist sites along the Atlantic coast on Tuesday, widening what may be France's largest peacetime evacuation as returning heat threatened firefighters' fragile hold on a vast wildfire west of Bordeaux. Fresh flames erupted near Grand Crohot on the Lège-Cap-Ferret peninsula, prompting a fleet of 23 planes and helicopters to drop water and fire retardant. Gironde prefect Sophie Brocas said the situation remains complicated, though about 60,000 residents evacuated from Le Haillan and parts of Mérignac and Eysines could return, but were told to keep emergency bags packed.
