Nuclear submarine fire

A fire has broken out at a shipyard near the Russian port of Murmansk, in which a nuclear-powered submarine is being repaired, say Russian media.

Officials say no leak of radiation has been detected, according to the RIA Novosti news agency. Some local media reports say the fire is on the submarine itself, but there is no confirmation of this. The authorities in the region say eleven fire crews and a navy launch are at the scene.
