A Major Incident has been declared on the moors above Manchester, as fire crews battle with a huge grass fire on Saddleworth Moor.
More than 30 homes have been evacuated, and people are being advised to keep doors and windows shut. Those with asthma or other breathing problems should keep their medication with them at all times.
The fires which have been sweeping across Saddleworth Moor could last for weeks unless there's a significant spell of rain.
That's the warning from the Greater Manchester Fire and Rescue service on day 5 of the emergency.
Union says the growing risk represents "another strain on dwindling resources."
The massive moorland fire in Saddleworth is now being investigated as arson.
More than 100 firefighters from Greater Manchester Fire and Rescue Service are continuing to battle against 'unprecedented' moorland fires.
