Dr. Usman’s “ustaad” was none other than the recently killed Ilyas Kashmiri, who was an SSG commando (jawaan not officer).
Two former Army officers from the same group were also involved in killing former SSG commandant Maj.Gen (Rtd) Amir Faisal Alvi because he was a Shia and publicly opposed peace treaties with the Taliban and also due to the SSG role in clearing Lal Masjid.
