FIREFIGHTERS have worked through the night to tackle a blaze which damaged a building. 

A "massive fire" took hold of the derelict site on the corner of High Street and George Street at around 1.30am. 

Around 40 firefighters were sent to tackle the inferno and images shared online show flames engulfing the night sky. 

UPDATE: High Street: Firefighters remain at the scene of blaze which tore through building near Old College Bar

Parts of High Street, Duke Street, and George Street are closed to traffic and trains weren't calling at High Street station for much of this morning. 

Four fire engines were initially sent to the scene but they soon called for back-up, with another three appliances and two high reach vehicles dispatched.

A Scottish Fire and Rescue spokeswoman said: “We were alerted at 1:27am on Tuesday, May 4, to a report of a derelict building on fire at High St, Glasgow.

“Operations Control immediately mobilised four fire appliances to the scene. Firefighters were met with a well-developed fire and requested further resources to bring the fire under control.

“At its height more than 40 firefighters, seven fire engines and two height appliances were in attendance.

“There are no reported casualties and crews continue to work to extinguish the fire."
