A group of 20 schoolchildren missing in the Brecon Beacons in south Wales, have been found and a rescue helicopter is with them on the mountain, police have said.
The group is from England and was in the area as part of their Duke of Edinburgh award.
Search teams received a call alerting them to the situation at around 1pm following heavy rain.
Late Wednesday afternoon, Dyfed-Powys Police confirmed the children had been located, but added "we cannot confirm that all in the group are accounted for".
The group's general whereabouts is said to have been known but, earlier, they were unable to be located due to cloud.
The children, who are in several groups, were last seen near Tafarn Y Garreg, Abercraf, Powys, Sky News reported.
Two are thought to be suffering from hypothermia.
It was initially reported the group was lost in underground caves but this was later retracted.
The Central Beacons Mountain Rescue Team is leading the search operation, assisted by a UK Coastguard helicopter.
