"Human Rights Watch estimates that Saddam's 1987-1988 campaign of terror against the Kurds killed at least 50,000 and possibly as many as 100,000 Kurds. o The Iraqi regime used chemical agents to include mustard gas and nerve agents in attacks against at least 40 Kurdish villages between 1987-1988. The largest was the attack on Halabja which resulted in approximately 5,000 deaths. o 2,000 Kurdish villages were destroyed during the campaign of terror."
