In mid‑July 2026, French authorities detained six people in connection with the July 2024 Moulins district fire in Nice that killed seven family members. The prosecutor stated, “six personnes sont mises en examen et placées en détention provisoire en France.” One detainee, a 23‑year‑old, admitted to a limited role as an intermediary but claimed he was threatened. Two suspects remain at large—one in Algeria and another in Guinea‑Bissau—both shielded from extradition due to the lack of bilateral agreements. Investigators allege that a 26‑year‑old man, Yassine K., organized an armed commando from his prison cell to carry out the Nice attack, which was reportedly motivated by drug trafficking disputes. By the end of July, detention actions expanded to other arson cases. In Larmor‑Plage, France, a 26‑year‑old was placed in pre‑trial detention after admitting to igniting multiple vegetation fires, including a blaze at the Kerguelen coastal park. Simultaneously, Canadian police in Laval arrested Simon Hudon, 42, and Ayoub‑Éliasse Saad, 23, for deliberately setting fire to a residential building in the Sainte‑Dorothée neighbourhood. In August, French authorities detained a 15-year-old in connection with a forest fire near Bordeaux-Mérignac airport that killed two firefighters, Wilfried Schmitter and Anthony Berthôme. This incident, following the death of a volunteer firefighter in Savoie, has intensified tensions within French emergency services, with unions protesting resource shortages and threatening industrial action. By mid-August, French authorities reported detaining 474 people, including 183 minors, in connection with wildfires since July 1. Regarding the Bordeaux airport fire, the 15-year-old suspect admitted to throwing a cigarette butt at the site, leading to charges of involuntary destruction by fire causing death. The teenager has been placed in a closed educational center. Meanwhile, Yassine K. has been placed in custody for his alleged role in the Nice arson attack.
