The US and Australia are joining the search for a submarine missing off Bali with only hours left before it runs out of oxygen. The German-built Nanggala 402 is carrying 53 crew.
Indonesian navy ships on Friday stepped up their hunt for a missing submarine as fears grow that its 53 crewmembers might die from lack of oxygen.
Altogether, 24 navy and other ships, along with a patrol plane, are scouring the seas off the island of Bali. They were to be joined later by two Australian warships, while the United States says it has sent aircraft to help.
Singapore, Malaysia and India say they are also helping in the hunt.
