14 August 2013 Last updated at 15:44 BST

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.
