Indonesia has launched search efforts for a navy submarine which has gone missing with 53 people on board, officials say.
The submarine was conducting a drill in waters north of the island of Bali but failed to report back the results.
Indonesia’s military chief said warships had been dispatched to find the KRI Nanggala-402 vessel.
Officials have called on Australia and Singapore to help in the search. The countries have not publicly commented.
The German-made submarine is thought to have disappeared in waters about 60 miles (96km) off the coast of Bali early on Wednesday morning.
“[The navy] is currently searching for it. We know the area but it’s quite deep,” First Admiral Julius Widjojono told AFP news agency.
