Firefighters have been called to battle a blaze at the BBC studios in Glasgow.
Emergency services were alerted to the fire within a utility room shortly before 11.30am on Sunday.
Workers were evacuated from the Pacific Quay building and have been sent to the Crowne Plaza hotel on the other side of the River Clyde.
BBC Radio Scotland’s Off the Ball programme, which was being broadcast at the time of the incident, was taken off air and replaced with a “network programme”.
Pictures from the scene show smoke billowing from the roof.
The Scottish Fire and Rescue Service (SFRS) told STV News that five appliances have been sent to tackle the flames, including a specialist high-reach vehicle.
The spokesperson said: “We were alerted at 11.26am on Sunday, January 31 to reports of smoke issuing from the roof of a commercial building in Glasgow’s Pacific Quay.
“Operations control has mobilised four fire appliances and an aerial platform to the scene.
“Firefighters are currently trying to extinguish a fire that has taken hold within a utility room on top of the roof.”
