He is set to be transferred to Morriston Hospital in Swansea.

Neighbours heard a huge bang just after 1300BST and saw one of the men running from the house at Meadow Rise, Brynna, near Pontyclun with serious injuries to both his arms and burns to his face.

Neighbours said the house was owned by a couple in their 40s and it was believed the owner and a friend were injured in the blast.

One of the victims was thought to have been in the kitchen, while the other person was in the front room of the property.

Electrical fault

Gas and electricity experts are now at the scene of the explosion, but its cause was not yet known.

Police and fire officers cordoned off the street and nearby homes were also evacuated.

Emergency accommodation was being found for residents by the local council.

Gas utility company Transco has sent an engineer to the scene.

South Wales Police Inspector Joe Ruddy said: "We believe it was an electrical fault and that the man has sustained burn injuries."
