Around 60 firefighters tackled a fire that took hold at an Asda supermarket in the early hours of Sunday morning.
The blaze, which tore through the roof of a branch in Newham, East London, lasted for nearly three hours.
No one is understood to have been harmed.
According to the Metro, firefighters were seen using an angle grinder to cut a hole in the shutters at the front of the store.
A crane had to be used to get them close to the flames, which began in the rafters and would eventually destroy part of the roof.
It is not known what caused the fire to break out in the supermarket, which was closed at the time.
The London Fire Brigade (LFB) was called at just past 4am and had brought the blaze under control by around 7am.
Pictures from the scene this morning showed charred debris littering the entrance to the shop.
In an earlier statement, LFB said: “Eight fire engines and around 60 firefighters are dealing with a supermarket fire on Tollgate Road in Beckton.
“Fire crews from East Ham and surrounding fire stations are at the scene.
“The cause of the fire is not known at this stage.”
Around 800 staff were evacuated from Ocado’s Erith warehouse in July after the collision of three grocery-packing robots sparked a fire.
The retailer was forced to cancel orders for days afterwards and haemorrhaged £35 million in lost sales.
