Indonesia’s military on Sunday officially said all 53 crew members from a submarine that sank and broke apart last week are dead, and that search teams had located the vessel’s wreckage on the ocean floor.

The grim announcement comes a day after Indonesia said the submarine was considered sunk, not merely missing, but did not explicitly say whether the crew was dead. Officials had also said the KRI Nanggala 402′s oxygen supply would have run out early Saturday, three days after vessel went missing off the resort island of Bali.

“We received underwater pictures that are confirmed as the parts of the submarine, including its rear vertical rudder, anchors, outer pressure body, embossed dive rudder and other ship parts,” military chief Hadi Tjahjanto told reporters in Bali on Sunday.
