A major fire breaks out at an industrial estate near St Albans, prompting emergency action and the closure of part of the M25. Thick smoke rises and drifts over the motorway, with authorities issuing warnings to drivers.

Multiple outlets report that the M25 is shut in the area between Junction 22 and Junction 21a. They describe the smoke plume as significant and visible from the road, and they note public safety messaging that advises motorists to “shut windows.” The Daily Mail also highlights concerns that an “explosion” could occur, reflecting fears related to the fire’s proximity to the motorway and potential hazards on the site.

While coverage focuses on the same incident—an industrial fire affecting the M25—outlets emphasize slightly different aspects. The Mirror leads with the motorway closure and the smoke/driving warning, while the Daily Mail foregrounds the closure details and the possibility of an explosion. All accounts agree the situation involves active firefighting and transport disruption due to smoke in the immediate vicinity of the motorway.
