Six hundred metres square of grass and woodland were alight. There were no reports of any injuries.

The cause of the fire is not known at this stage.
If you see a grass fire, don't attempt to put it out yourself as grass fires can travel very quickly and change direction without warning. Call the fire Brigade and let us know where the fire is.
