49 deliberate grass fires in 12 hours in south Wales
A fire service said it has had to deal with 49 deliberate grass fires in just 12 hours.
Firefighters at South Wales Fire and Rescue Service have been called to various locations to tackle the blazes.
One included a mountain fire which spread to 1,000 tyres on farmland in Ynyshir, Rhondda Cynon Taff.
During the same period on Wednesday, the service received 500 calls and 73 fire engines have been used while crews are said to be "exhausted".
Nigel Williams, a spokesman for South Wales Fire and Rescue Service told BBC Radio Wales' Good Morning Wales it is a particular problem.
