LONDON (REUTERS) - A rescue mission has been launched to find 24 children lost in the Brecon Beacons, a mountainous area in Wales, the BBC reported on Wednesday (June 29).

Three mountain rescue teams and police are taking part in the search around Tafarn Y Garreg, near Abercraf.

Mark Moran from Central Beacons Mountain Rescue said the team believes it knows where the children are, but they are lost in the clouds, BBC reported.

Two are thought to be suffering the effects of hypothermia.

The four groups of six children from England are in their mid teens and are on the beacons as part of their Duke of Edinburgh Award. They were not accompanied by adults.
