The search for a missing submarine in Indonesian waters
A search for an Indonesian submarine that went missing with 53 crew on board off Bali continued on Thursday after rescuers found an oil slick and neighbouring countries pledged to help.
The German-made, diesel-powered submarine, named the KRI Nanggala-402, is one of five submarines in Indonesia's fleet.
The vessel can sustain a depth of 250-500 metres (820-1640 ft) but there are concerns it is currently lying at a depth of 600-700 metres, military officials said.
