UK storms: Warning over sand dune 'cliffs' at Cefn Sidan

5 February 2014 Last updated at 13:23 GMT

Beach walkers have been warned to avoid sand dune "cliffs" created by recent storms on the Carmarthenshire coast due to the risk of collapse.

Shifting sands have created dunes of up to 35ft (10m) high along an eight mile (13 km) stretch of Cefn Sidan beach.
