Rescue teams from across the UK have arrived in Wales to free a man trapped in a cave for two days.
The South and Mid Wales Cave Rescue Team said the man fell while caving in Ogof Ffynnon Ddu, a cave system near Penwyllt in the Brecon Beacons on Saturday.
Because of the injuries he suffered in the fall he is said to be unable to climb out of the cave.

The emergency service was notified by another caver and since then at least eight rescue teams from across the UK have joined the operation.
Involved are the Gloucester Cave Rescue Group, Midlands Cave Rescue Organisation, Derbyshire Cave Rescue Organisation, Mendip Cave Rescue, South East Cave Rescue Organisation, the Cave Rescue Organisation, and Upper Wharfedale Fell Rescue Association.
Located inside a nature reserve, Ogof Ffynnon Ddu – meaning Cave of the Black Spring – was discovered in 1946 and is 300m deep at its lowest point, with its underground caverns stretching to over 30 miles.
Only experienced cavers are granted permission to explore inside.
