Several roads in Glasgow city centre remain closed as firefighters tackle the remains of a major blaze close to The Barras market.
Strathclyde Fire and Rescue was called to the incident, at a row of shops on Gallowgate, at 2230 GMT on Thursday.
The fire was brought under control by four appliances and more than 60 officers who worked through the night.
Dozens of firefighters are still tackling "pockets of fire" across several buildings.
The operation was scaled down at 0600 GMT, but 25 firefighters and four appliances are still at the scene.
The fire service said "a considerable amount of damage" had been caused by the blaze, which broke out the back of the row of two-storey shops.
The front wall of one of the shops has partially collapsed.
It is thought that the total area affected by the blaze covers about 100m (328ft) by 50m (164ft).
A fire service spokesman said: "The firefighters were met with difficult and dangerous conditions.
"Due to their sheer tenacity and courage, they brought the blaze, which involved the basement and ground floor of the two-storey building, with a partial collapse of the front of the building, under control."
Several surrounding roads are likely to remain closed until at least midday.
Glasgow City Council said Gallowgate was closed eastbound between Glasgow Cross and Moir Street.
An investigation into the cause of the fire will start once it has been fully extinguished.
