Nine teenagers, some reportedly suffering from hypothermia, have been rescued by an RAF helicopter from the Black Mountains in mid Wales.
The teenagers were flown to a hospital in Merthyr Tydfil
The group of boys and girls, all aged 15 or 16, were taking part in the Duke of Edinburgh award scheme.
The teenagers, from King Alfred School in Highbridge, Somerset, were then taken to hospital in Merthyr Tydfil.
One of them had called police to say they were in difficulties and two forces combined efforts in the rescue.
The helicopter, Rescue 169 based at RAF Chivenor in Devon, was scrambled to help the search.
Dyfed-Powys Police were involved in the operation along with Brecon Mountain Rescue Team and Longtown Mountain Rescue Team, based at Monmouth.
