The 15th of March marked the 16th anniversary of Saddam's chemical gas attack at Halabja.
Iraq's US governor Paul Bremer has promised the country's Kurds that Saddam Hussein and his aides will face justice for a chemical attack that killed 5,000 people.
The poison gas attack on Halabja in 1988 is the most notorious chapter in a brutal campaign waged against the Kurds to punish them for pushing for autonomy in the north.
Mr Bremer has assured the Kurds that Saddam and Ali Hassan Majid, known as "Chemical Ali" would answer for their actions.
He says the incident 16 years ago serves as proof that last year's US led invasion of Iraq was justified.
"For those in my country and elsewhere who unaccountably still wonder if the war was worth fighting, come to Halabja," Mr Bremer said.
"Come see the tombstones of the 5,000 men, women and children who died here.
"Look in the faces of the survivors here today.
"See how a peaceful village was turned into a hell overnight by evil."
