Visible for kilometres around, a thick gray and black smoke rose into the sky over the Île-de-France region on Thursday, July 9, 2026, in the late afternoon. This has unsettled residents who pushed questions onto social networks. So what exactly happened? A fire is at the source of the smoke plume observed on the eastern side of the capital, confirming the suspicions of those who watched from afar. The blaze broke out in the suburban belt of Paris, more precisely in Créteil, in the Val-de-Marne, at the Essilor site, a company specializing in lenses and ophthalmic equipment. Emergency services are already on the scene, and in social media posts you can see striking footage of flames and rising smoke.
It is advisable to avoid the area near the departmental road D1. The exact cause of the incident remains unknown, with authorities describing it as a "fire of medium intensity in an office area". So if this smoke alerted you, you now know more about what happened.
