A group of at least 20 schoolchildren were reported missing in the Brecon Beacons, with two of the party believed to require medical attention due to hypothermia. The children are not accompanied by an adult.
Police, rescue helicopters and mountain teams are believed to have located 14 members of the party, while at least six are confirmed still missing and are thought to be at cloud level around Tafarn Y Garreg, north of Abercraf, Powys.
Local landlord, Andy Maglaras, told Press Association 14 of the children were expected at his pub, saying: "I think they were on a school trip, we get quite a few around here.
"We are just waiting for them to come down, they are up on a trail. We are getting some hot juice ready for them.
"They have told us they will be bringing the children here and to get them something hot to drink and keep them by the fire."
The alarm was raised at around 1pm today (29 June), when the children were initially thought to be lost in underground caves. It is now believed they are lost above ground, possibly hidden by cloud.
The group has reportedly been spotted by the rescue helicopter, but is sending people to the location on foot as there is nowhere safe for the helicopter to land.
It has been reported that at least two of the children in the group are suspected of having hypothermia, with several 999 calls made reporting the group lost.
A Dyfed-Powys Police spokesman told the BBC: "Concern was expressed for their welfare due to the inclement weather.
"Mountain Rescue Team are leading the search activity and the UK Coastguard helicopter is also assisting."
The children, who are from England, are believed to be on a Duke of Edinburgh Award activity and have made contact with rescuers who are believed to have an idea of where they are, but is currently unable to see them due to heavy cloud.
