32 detained in France over suspected forest fire-starting

Thirty-two people have been detained across France on suspicion of causing wildfire outbreaks, as authorities investigate the role of human activity in the country’s severe ongoing fire season.

“Those unacceptable behaviours, which generate disastrous consequences and mobilise our firefighters at the risk of their lives, now fall under the responsibility of the justice system,” said Interior Minister Laurent Nuñez as he announced the detentions on July 11. “We will not let anything pass.”

The cases, spread across 22 departments, do not all involve suspected arson. Authorities are investigating a range of circumstances, including accidental fires and deliberate acts.

More than 8,000 wildfire outbreaks have been recorded since the start of 2026, with more than 25,000 hectares burned, according to France’s Civil Security Directorate (Sécurité civile).

Nine out of 10 fires linked to human activity

President Emmanuel Macron said nine out of 10 wildfire were caused by human activity, whether through negligence or deliberate action.

“One second of carelessness can threaten families, put those who protect us in danger and destroy our landscapes,” he said on X

Around one third of those detained are minors, according to news outlet BFM. 

However, investigators are examining a wide range of cases, with some fires believed to have been accidental, including those linked to barbecues or agricultural equipment, while others involve suspected deliberate acts or personal disputes.

In Hérault, a 27-year-old man with a previous conviction was arrested after a fire near Lunas. Prosecutors said he later admitted accidentally starting the blaze while burning a personal letter.

Three of the people detained have been placed in pre-trial detention, and some suspects are reported to have previous links to fire-setting.

Authorities urge caution during high-risk period

Fire officials have repeatedly warned that everyday activities can trigger devastating blazes during periods of heat and drought.

People are advised not to use barbecues near vegetation, to dispose of cigarette ends safely and to avoid work that could create sparks close to dry grass or woodland.

With France recording unusually high levels of wildfire activity this year, authorities say preventing human-caused fires remains one of the most effective ways to reduce pressure on emergency services.
