NEW DELHI- About 18 Indian sailors were trapped after an explosion and fire on board a conventionally powered Indian submarine berthed at the coastal city of Mumbai early on Wednesday, the navy said.
"There are some people who are trapped on board, we are in the process of trying to rescue them, we suspect it to be in the range of 18," said navy spokesman PVS Satish.
"We will not give up until we get to them," Satish said.
The explosion inside the INS Sindhurakshak was likely an accident, Satish said. Photos distributed by social media users appeared to show a large fireball over the navy dock where the diesel-electric submarine was berthed.
