Mountain rescue teams joined a major search for a missing paddler in the Brecon Beacons.
The kayaker got into difficulties on the River Usk near Llangynidr, downstream of Talybont about 1pm today.
The man, in his 30s, was with a group of paddlers on the river.
Dyfed-Powys Police said the force’s helicopter joined the operation, along with volunteer mountain rescuers, the Coastguard, a search and rescue helicopter and Mid and West Wales Fire and Rescue Service.
A police spokesperson said: “His family have been informed. The families of the rest of the kayaking group, who are safe and well, have been informed.
“Weather conditions are very difficult and challenging at the scene.
“All efforts are being made in the on-going search and rescue operation. We advise people to stay away from the scene for their safety due to the conditions.”
