More than 70 firefighters are battling a blaze at an industrial bakery in London.
The building, a single-storey industrial unit in Tottenham, north London, is "100% alight", a spokeswoman for London Fire Brigade said.
The front of the building has partially collapsed, but no-one is believed to be injured, she added.
Images posted on social media show huge clouds of smoke billowing above the surrounding area.
Firefighters are still tackling the blaze, on West Mews, using jets to protect a 2,000-litre diesel tank and prevent the fire from spreading to neighbouring factory units.
Four people from a nearby building who were unaccounted for were located by the fire brigade. After being assessed by London Ambulance Service, they did not require treatment.
People living near the bakery are being advised to keep windows closed "as a precaution" due to the smoke.
