Analysis of information sources in references of the Wikipedia article "Pakistan Navy" in English language version.
Pakistani authorities say the submarine sank because of either an internal explosion or accidental blast of mines that the submarine itself was laying around Vizag harbour.
On December 9, the Navy announced that they had sunk the Ghazi on December 4, after the start of the war. Later, officers were decorated for their role and the offensive action of their ships in the sinking of the Ghazi. After the war, however, teams of divers confirmed that it was an internal explosion that sank the Ghazi. The log of the Ghazi was recovered and the last entry as far as I can recall was on November 29, 1971. Sadly, that too has been destroyed.
