Indian Defence Minister AK Antony has described two huge explosions and a fire on an Indian submarine berthed at a Mumbai dockyard as a "shocking tragedy".
Navy chiefs earlier warned the families of 18 sailors on board the submerged vessel to "prepare for the worst" after the two near-simultaneous explosions.
Mr Antony offered "heartfelt condolences" to relatives of the dead.
It is not clear what caused the blasts. Sabotage has not been ruled out.
