Dozens of firefighters poured water onto a big fire early Monday at Camden Lock Market, which is a popular tourist destination in north London.
The London Fire Brigade said 10 firetrucks and 70 firefighters had been sent to the site shortly after midnight Sunday when a blaze erupted near Camden Stables. It said three floors and the roof of a building within the complex were on fire.
Seventy firefighters were called to battle the blaze, the brigade said. Three stories and the roof of one building were affected by the fire, according to an update from the department on Sunday night.
"#CamdenMarket fire update: the 1st, 2nd and 3rd floors, plus the roof, of a building within the market are alight," the department tweeted on Sunday night.
Ambulance crews also rushed to the scene, but authorities said no injuries had been reported.
The market is very popular with tourists and Londoners, who are drawn to the area by the shopping and nightlife on offer.
"The fire was moving very fast," said witness Joan Ribes. "People were watching, but we were scared the building could explode at any time since there are restaurants with kitchens nearby."
A different part of the market complex was ravaged by a fire in 2008, and vendors were not able to operate for several months.
Monday's fire came less than four weeks after a fast-spreading blaze engulfed the Grenfell Tower apartment block in west London, killing at least 80 people.
