A man who witnessed an Abercarn schoolbus leave the road in icy conditions this morning says the 16 children and three adults on board had a 'lucky escape'.
Fire crews are still working to rescue the bus, which is trapped on a verge in the village of Llanfach.
It helps there were so many trees to stop the bus falling further down the cliff.
I expect there are a lot of kids in shock - and their parents as well.
