'Authentic evidence': Grim discovery in search for missing submarine

Indonesia's navy says items have been found from a missing submarine, indicating the vessel with 53 crew members has sunk.

Navy Chief Yudo Margono said on Saturday rescuers found several items including parts of a torpedo straightener, a grease bottle believed to be used to oil the periscope and prayer rugs from the submarine.

"With the authentic evidence we found believed to be from the submarine, we have now moved from the sub miss phase to sub sunk," Admiral Margono said.

Indonesia earlier considered the 44-year-old KRI Nanggala-402 submarine that disappeared on Thursday off Bali as just missing.

But it now declares the submarine as officially sunk with no hopes of finding any survivors.

Officials said oxygen supply for its 53 crew ran out early on Saturday (local time).
