LEGE-CAP FERRET, France (AP) — French authorities ordered nearly 4,000 people evacuated Tuesday from tourist sites on the Atlantic coast as returning heat threatened firefighters’ fragile hold on a vast wildfire west of Bordeaux.

The new evacuations deepened a wildfire emergency of exceptional scale across southwestern Europe. Fires in France and Spain have forced roughly 330,000 people to evacuate, while Spain entered its fourth heat wave of the summer with several blazes still out of control, including its largest on record.
