A submarine missing since Wednesday off the coast of Bali with 53 people on board has been lost, the Indonesian navy said on Saturday.
Parts of the submarine, along with debris, including prayer mats, were found near where it disappeared, said the Navy chief of staff.
A scan detected the submarine at a depth of 850m (2,800 feet), well beyond its survival limit.
He carried enough oxygen for just three days.
KRI Nanggala disappeared after requesting permission to dive during a torpedo exercise. The German-built ship was over 40 years old, but underwent a renovation in 2012.
The Indonesian navy insisted that the submarine was in good condition, but an oil slick where the ship is believed to have been submerged raised concerns that the fuel tank may have been damaged.
“We found several parts and pieces that are believed to be parts or components that are attached to the submarine that would not leave the ship without external pressure or a crack in the torpedo launcher,” said Staff Chief of Staff Yudo Margono.
Among the items recovered was a bottle of grease to lubricate the periscope. They were found within a 10-mile (16 km) radius where no other ships had passed.
There was an international effort to locate the Navy boat.
