The Scottish Fire and Rescue Service has been dealing with a wild fire near Glencorse Reservoir near Penicuik since earlier this afternoon.
Edinburgh Operations Control received a call just before noon and sent two appliances from Penicuik and Sighthill fire stations.
Due to the fire being fanned by the wind, further appliances from Dalkieth, Liberton and West Linton have also gone to assist.
Firefighters are still tackling the fire, which is in an area measuring 500m, with two main jets, a light portable pump and beaters.
The incident is ongoing and may be for some considerable time.
The area is popular with hill walkers and the fire service have asked everyone to avoid the area until fire operations are concluded.
