Today's roundup: the huge wildfire in southwest France is finally easing up, a new investigation looks at why it grew so large in the first place, and in Los Angeles, wildfire survivors and developers are fighting over how the burn zones get rebuilt.

France's Bordeaux wildfire is stabilizing, and evacuees are heading home

Firefighters in southwestern France are working through the last hot spots of a wildfire that has burned about 42,000 hectares (roughly 162 square miles) of pine forest and tourist areas in the Gironde region near Bordeaux, as the Associated Press reports. Lower overnight temperatures and higher humidity have helped crews get ahead of the fire, which hasn't spread in several days. Ukraine is sending 70 civil security personnel and 10 vehicles to help.

The fire initially forced 224,000 people to evacuate. Authorities have now let 144,000 of them return, and on Thursday gave the go-ahead for another wave of evacuees to head home, according to a separate report. Regional health authorities are recommending returnees wear gloves and face masks while they clean up ash, and France's public health agency reported a spike in asthma-related cases in the Bordeaux area over the weekend. Elsewhere in Europe, firefighters were also battling blazes Thursday in the UK, Spain, Germany, Greece and Turkey amid an unusually hot, dry summer.

Why the fire grew so big: unenforced firebreak rules

A New York Times investigation looks at why this fire spread so far, and points to long-ignored forestry rules in the region, as the New York Times reports. After a 2022 fire in the same area, France required homeowners near the forest to clear vegetation within about 50 yards of their houses, with mayors authorized to fine those who didn't comply. Four years later, the paper found those rules were rarely enforced across 23 evacuated villages, often because residents couldn't afford the clearing costs or didn't own the land the brush was growing on. Prosecutors say the fire's initial spark came from a brush-clearing machine near a power line outside the town of Saumos, though the cause of its rapid spread is still under investigation.

In Los Angeles, wildfire survivors and developers clash over rebuilding

A year after Los Angeles's devastating wildfires, survivors from Altadena to Pacific Palisades and Malibu are increasingly at odds with developers over how their neighborhoods get rebuilt, as POLITICO reports. Many residents say "predatory developers" are using rebuilding rules meant for disaster survivors to build denser housing than their communities want. State lawmakers are pursuing new limits on that kind of rebuilding, while developers argue they're delivering housing survivors need and that Los Angeles' broader housing shortage demands. Gov. Gavin Newsom issued an executive order last summer banning a state duplex law in Pacific Palisades in response to resident concerns.
