Firefighters are tackling a large fire in a derelict mill on Rooley Moor Road, Rochdale.
Six fire engines were called to the former Turner Industrial Products site at 11.10pm last night.
Fire Service Group Manager Tony Holt, who is in charge of the incident, said: "We have the fire under control, but we will be here all night and into tomorrow.
"Our specialist environmental protection officers are working with the Environment Agency and other partners to keep the environmental impact of this fire to a minimum.
"As a precaution we are asking everyone who lives nearby to keep their doors and windows closed, while we tackle this fire."
