"Body of one more sailor was recovered from the submarine late this evening," Navy sources said.
The divers had managed to open a second access to the sunken vessel during an overnight operation.
Sources said the Navy divers are carrying out the task of searching within the submarine by "feeling each inch" due to zero visibility within flooded compartments to locate the missing bodies and mark a probable route to be used for further rescue operations.
18 Navy personnel, including three officers, were on board the Russia-made submarine when a devastating fire ripped through the frontline underwater craft following serial explosions on Tuesday midnight. The Navy has instituted a Board of Inquiry to probe the cause of the explosions and fire which is expected to submit its report within four weeks.
Mumbai Police have also registered a case of accidental death in connection with the worst peacetime tragedy suffered by the Navy.
