A Russian nuclear submarine has caught fire in the northern province of Arkhangelsk ... The blaze started in the early afternoon local time when insulation between the craft’s inner and outer hull caught fire during welding. The submarine was the Oscar class K-266 Orel (Eagle), a similar vessel to the Kursk, which sank in the Barents Sea in 2000, claiming the lives of 118 men. A spokesman for the shipyard told Interfax there were no casualties and all crew and workers left the craft in time.
