Mustafa Barzani
Nadhim Kzar was named director by Saddam Hussein in 1969 after the DGS had deteriorated under 10 years (1958–1968) of army rule. Kzar was known for his sadism, and during his term the DGS tortured and killed thousands. Much of this violence was directed against the Iraqi Communist Party and Iraqi Kurds; Kzar twice attempted to assassinate Kurdish leader Mustafa Barzani.
