More than 50 firefighters have spent the night battling a blaze at a former asbestos factory in Rochdale.
Crews were called to the derelict mill just after 2.45am this morning.
Residents were advised to close doors and windows as a precaution due to the sheer amount of smoke the fire was creating.
Greater Manchester Fire and Rescue Service is continuing to work at the scene.
As well as firefighters who are working to put the fire out, specialist officers – such as hazardous materials officers – are there to help ensure the safety of those working at the site, those living nearby and the environment.
Local road closures remain in place.
