The Indian Navy has said that two explosions yesterday on INS Sindhurakshak, a Russian-built Kilo-class submarine, have trapped up to eighteen of its sailors. Navy officials have warned the families of trapped sailors to “prepare for the worst”.

The stricken vessel sank in its berth in Mumbai with only a small portion still visible on the surface. The cause of the explosion is still unclear.

A fire that started as a result of the explosions has been brought under control and other sailors that managed to escaped received attention from emergency personnel. Divers are attempting to locate survivors and refloat the vessel.
