BALI, April 23 (AFP): Indonesia's desperate search for a missing submarine and its crew of 53 honed in on a signal from an unidentified object Friday, with just hours to go before the stricken vessel's oxygen reserves ran out.

The ramped-up hunt comes as Australia and the United States are set to join the search off the coast of Bali where the sub disappeared more than two days ago during training exercises.
