Dozens of fire fighters have spent the night trying to contain a moorland fire on the Lancashire-Yorkshire border.
High winds have been fanning the flames after a fire broke out near a reservoir in Ripponden, West Yorkshire.
The blustery conditions are making it really hard for crews to tackle the blaze, which has spread at least two miles towards Greater Manchester.
Fire chiefs said two officers had been slightly hurt and warned members of the public to stay away.
The cause of the fire is not yet known.
