A rescue mission has been launched to find 20 children lost in the Brecon Beacons, a mountainous area in Wales, the BBC reported on Wednesday.
It cited Central Beacons Mountain Rescue as saying they believed they knew where the children were but that low clouds were hampering visibility. The rescue team was in intermittent phone contact with the children.
Two were thought to be suffering from the effects of hypothermia, the BBC reported, adding that a Coastguard rescue helicopter had been sent to the scene to help with the search.
No comment was immediately available from Welsh emergency rescue services.
