Nine people suffered smoke inhalation injuries in a fire which broke out in a tunnel beneath a fjord south of the Norwegian capital Oslo on Thursday, dpa quoted broadcaster NRK as reporting. The fire apparently originated with a lorry carrying a cargo of paper. The 7.2-kilometre-long Oslofjord tunnel near the town of Drobak south of Oslo quickly filled with smoke, with fire-fighters needing an hour and a half to extinguish it.
