Indonesia has deployed warships in the hunt for a navy submarine that went missing with 53 crew aboard off the coast of Bali, as other nations sent vessels to help with the search.
An oil spill where the vessel was thought to have submerged early yesterday during regular exercises could point to damage, the navy has said.
Navy spokesman Julius Widjojono said that search teams were focused on an area around the oil slick, but that the exact location of the vessel had yet to be pinpointed.
There were 53 crew members aboard the vessel, which was believed to be in waters about 700 metres deep.
French navy vice admiral Antoine Beaussant said earlier that the submarine was not built to withstand such a depth.
“If it went down to rest at 700 metres the likelihood is it would have broken up,” he said.
