A search has been launched for a kayaker missing in a river in Wales.
The emergency services were called to the River Usk at Llangynidr, near Crickhowell, Powys just after 1pm today.
Dyfed-Powys Police, the Welsh Ambulance Service and Brecon Mountain Rescue Team have also joined the search.
Water levels are understood to be high on the River Usk following heavy rain over the weekend.
