Firefighters are responding to a major fire at one of Britain's largest Jewish supermarkets in Golders Green.
Emergency services are in attendance at the Kosher Kingdom on Golders Green Road near the junction with Beverley Gardens.
The London Fire Brigade has advised residents to stay away from the area while fire crews tackle the blaze.
Detectives from the Met Police confirmed the fire is not being treated as suspicious and is believed to have been caused by an electrical fault.
A spokesman from the brigade said: "A number of road closures are in place, including on Golders Green Road near the junction with Beverley Gardens.
"Please avoid the area whilst firefighters work to extinguish the fire.
"The Brigade received the first of 33 calls about the fire at 6.47am.
"Control Officers have mobilised ten fire engines and around 70 firefighters from Finchley, Willesden, West Hampstead and surrounding fire stations to the scene. A 32-metre turntable ladder is also in attendance."

Nearby businesses said they thought the fire broke out due to an electrical surge in a warehouse near the property.
Sami Joseph, manager of Gross Butchers next door, told LBC: "It's been a bad year in Golders Green. Month after month, there is some sort of incident. First you got the ambulance, then you got the stabbing, and now this.
"People assume it's maybe a terrorist or arson or something like that, but I think one of the staff said he was the electricity. Someone said it could be the electrics - there's been a surge - because it's happened before about 15 years ago.
"I think it's the circuit board and I think it's been related to the heat the last two days, and there's been a surge and it caused a spark."
