The search for a missing Indonesian submarine has turned into a salvage operation.
The 53 crew members are now presumed dead after the submarine's debris was found.
The vessel was declared "sunk" on Saturday, four days after it disappeared.
President Joko Widodo said on Sunday that all Indonesians express their deep sorrow over this tragedy, especially to the families of the submarine crew.
