Tragic Explosion in Trévoux Residential Building Leaves Two Children Dead and Several Injured

On the evening of December 15, 2025, a devastating explosion struck a four-story residential building in Trévoux, Ain, resulting in at least six victims, including the tragic deaths of two young children aged three and five. The incident occurred around 5:30 PM and has prompted an extensive emergency response.

The explosion, attributed to a gas leak, caused severe damage to the building and shattered windows in two nearby schools, though fortunately no injuries were reported at those institutions. The prefecture swiftly activated the NOVI (mass casualty) plan to coordinate rescue efforts, deploying 50 firefighters and 36 emergency vehicles to the site. Authorities also set up a security perimeter and urged the public to avoid the area for safety reasons.

Rescue teams are actively searching the building for additional victims. Several people affected by the explosion have been evacuated and are now being accommodated in a reception center, where a psychological emergency unit has also been mobilized to support those traumatized by the event.

Local reports indicated that the two youngest victims were found in cardiac arrest and subsequently died from their injuries. The prefecture confirmed that other victims are receiving medical attention on-site, though detailed information about their conditions remains limited.

This tragic event has deeply affected the community, which continues to cope with the aftermath. Emergency services remain on high alert as they conduct ongoing investigations and support recovery efforts.

The prefect of Ain emphasized the dedication of all rescue services working to manage this critical situation, while the public is advised to stay clear of the affected area to allow emergency personnel to operate efficiently.
