As per NDTV video. there seems to be more than 2 explosions in the video. also first hand report from fire fighters suggestive of extensive damage to naval dockyard itself . Does Multiple explosions as seen in video point towards involvement of torpedoe section ? This is very serious-given the intensity of explosions likelihood of survivors greatly diminishes and sub is likely to be damaged extensively- perhaps beyond repair.
if that is true ... then emotionalism apart.... sailors were gone...
