A tenement building has collapsed after a fire broke out in a ground-floor shop.
Fire crews worked through the night after the blaze started at the Strawberry & Spice Garden grocery in Albert Drive, Glasgow, around 11.30pm on Sunday.
Nine fire engines and two height appliances were sent to tackle the blaze, which was so severe it caused the building to collapse.
Roads in the area were closed as emergency services dealt with the incident in the Pollokshields area of the city.
Residents were evacuated from the flats above the shop as fire crews tackled the blaze, and one person was taken to hospital suffering from the effects of smoke inhalation.
First Minister Nicola Sturgeon said it was a "dark day" for her constituency.
She told STV News: "I just want to convey my thanks to the fire service and to the police for the incredible work they have done here overnight to make sure that nobody was seriously injured or killed in what is an absolute tragedy for Pollokshields.
"There are people obviously who have lost their homes, a number of businesses affected, that corner is an iconic part of the local community, so my thoughts are with everybody affected.
"Obviously as the local MSP, I stand ready to offer any advice and assistance I can to those who are affected, but this is a dark day for Pollokshields and everybody affected is very much in my thoughts."
Emergency services were still at the scene on Monday afternoon.
The Scottish Fire & Rescue Service (SFRS) has conducted enquiries and do not believe anyone was inside at the time of the blaze.
Inspector Mags Brennan, who is leading the police response, said: "While we appreciate the disruption to the local community, road closures are in place for safety reasons and will remain there for the foreseeable.
"While our partners are confident that there are no casualties, a joint investigation into the cause of the fire is under way with the fire service and further updates will be provided when available."
SFRS incident commander, deputy assistant chief officer James McNeil, said: "This has undoubtedly been a challenging and protracted incident that required considerable resources to meet.
"Firstly, I would like to thank our crews for their efforts - working in difficult conditions throughout the night - in bringing this fire under control.
"I would also like to thank the community for their patience and support throughout the incident, and recognise the hard work put in by our partners, other emergency services and the local authority.
"The Scottish Fire & Rescue Service will continue to work alongside our Police Scotland colleagues to establish the full facts and circumstances of the fire."
Scottish Water tweeted that as fire hydrants were in use, this was causing "low pressure and discoloured water to the surrounding streets".
Nearby Pollokshields Early Years Centre was shut because it had no electricity following the blaze while Pollokshields Primary School was also closed.
Glasgow City Council said that arts venue Tramway was made available to anyone who needed somewhere to go during the incident.
A council spokeswoman said: "A rest centre is still in operation at Tramway where residents are being offered assistance and advice from our staff, and we will continue to liaise with the emergency services.
"Our building control officers are on site. Pollokshields Primary School and Pollokshields Early Years Centre are closed today and the staff will keep families updated with information."
