The sailors from the ship stated that the ship did not explode itself, and the stern sank very (really) quick; whoever at the near stern were not able to escape from the ship.
Another wounded sailor said that the ship seemed break in two after the huge explosion. Then the ship started leaning to one side causing people and things falling to the sea.

One of the missing sailor fought during 2002 naval clash; he participated in combat despite the bullet went through his body.
