FIRE crews were called to the National Museum in Cardiff this afternoon after a blaze broke out in the building's dome.

South Wales Fire and Rescue Service deployed a crane to the front entrance of the museum, in Cathays Park, so that firefighters could reach the dome, which is 30 metres above the ground.

More firefighters were then seen on a section of scaffolding, inspecting a section of the dome.

Shortly after 1.30pm, museum staff confirmed via the site's Twitter account that the "small fire" had been "successfully extinguished".

Nobody was hurt and no collections were damaged in the fire, the museum said, adding that the source of the incident was now being investigated.
