A search is underway after a group of 24 schoolchildren went missing in the Breacon Beacons.
The group is reportedly lost near a cave system in the Welsh National Park and police have told The Independent they received several 999 calls to report that the group was in difficulties.
Three mountain rescue teams and a team of police officers have responded to the calls and are searching the area near Tafarn Y Garreg, north of Abercraf in Powys, according to the BBC.
The Coastguard rescue helicopter from RAF St Athan has also been drafted in to assist in the search.
The alarm was raised at about 1pm and Mark Moran from Central Beacons Mountain Rescue said the team believes it knows roughly where the group is, but they are lost in the clouds.
Two of the group are thought to be suffering the effects of hypothermia, and Mr Moran said the rescue team is in intermittent phone contact with the four groups of six children – who do not have an adult with them, according to the BBC.
The children are in their mid teens and are on the mountain as part of their Duke of Edinburgh Award.
