Indonesian officials say debris from a missing submarine was found after the vessel sank as hopes of rescuing 53 sailors on board faded.
The search team on Sunday focused on pinpointing the sub’s exact location. Authorities warned any salvage operation would be risky and difficult in the deep waters.
Singapore’s MV Swift Rescue – a submarine rescue vessel – arrived to aid in the recovery effort, the navy said. Neighbouring Malaysia as well as the United States, India and Australia were among the nations helping in the search.
