A major fire broke out on board the INS Sindhurakshak submarine at the Mumbai Naval Dockyard late on Tuesday night. Officials say that an explosion caused the fire, but the cause of the explosion is not yet known.
Officials are puzzled after seeing the footage of the explosion. They say the visuals indicate that multiple blasts seem to have taken place outside the submarine.
There is no clarity on whether the fire is under control, but 18 personnel who were on board at the time of the incident are still feared to be trapped inside.
Efforts are on to ascertain their safety and salvage the submarine. At least 16 fire tenders are at the location apart from Navy's internal fire fighting team.
The Navy divers are also on the spot to ensure the safety of the personnel on board the submarine. It is a battle against time as the oxygen inside the submarine is limited for the people who are trapped inside.
A board of inquiry has been formed to investigate the case. Officials say the submarine is largely submerged under water now and a large part of it has been gutted.
"I heard a loud sound and then I saw smoke and fire," said an eyewitness. "I was at work when I heard a loud sound. The sky had turned red," another eyewitness said.
