At least nine people have been killed, and others are missing, following a fire during a club night, in the US state of California.
At least nine people have died in a fire during a club night near San Francisco, authorities say.
Oakland fire chief Teresa Deloach-Reed said at least another 13 people were unaccounted for.
The fire started at 23:30 local time on Friday (07:30 GMT Saturday) in Oakland, police told the BBC.
The venue was hosting a concert by electronic group Golden Donna. The event’s Facebook page indicates a number of people are missing.
Authorities told the local KTVU network about 50 people were inside the venue.
The total death toll remains unknown, but the Alameda County sheriff’s office said the coroner had prepared for more than 40 bodies.
The building housed artists in studios, it said. It did not appear to be a formal concert venue.
Deloach-Reed told reporters that the only exit from the second floor was a staircase made from wooden pallets.
She said firefighters did not hear smoke alarms when they arrived at the scene.
