Fire fighters were called to a blaze at an outdoor structure which contained two propane cylinders.

Four appliances from Wisbech, Downham Market, and Littleport fire stations attended the building off Flint House Road in Three Holes, near Wisbech, Cambridgeshire.

The outdoor structure measures 20 x 5m and crews used main jets and a thermal image camera to keep an eye on the cylinders.

Emergency services were alerted to the fire at 7.40pm last night.

Crews were still working at the scene at 11pm, a spokesman for Norfolk and Fire and Rescue Service said.

Further updates are expected today.
