A grass fire has destroyed a patch of farmland but the cause is unknown at this time, according to the London Fire Brigade (LFB). 

A fire broke out in Rainham yesterday afternoon (June 25) at a farm in South End Road, destroying an area of around 100 metres squared.

Four fire engines and 25 firefighers attended the scene.

The brigade was called at 3.22pm and the incident was over by 4.14pm.

A LFB spokesperson said no cause had been given for the fire yet, but urged people to refrain from barbecuing in open spaces and to throw away rubbish and stub out cigarettes safely.

LFB advice also encouraged people to avoid barbecuing on balconies as wind may carry smouldering ash towards neaby grassland.

Fire crews from Harold Hill, Bromley and Orpington fire stations were in attendance.
