PNS Ghazi

Hi  I found an official pakistani navy history.  apparently they like to hide it and not have any links to it on their main page.  It says Ghazi was 'lost' during mine laying operations and says NOTHING about any accidents. to quote 'The submarine actively participated in Indo Pak 1965 war but was lost in 1971 war while deployed on a mine laying operation off the Indian Coast.'.
