Saddam Hussein and his former top army commanders will go on trial on August 21st on charges of killing tens of thousands of Iraq's Kurds in 1988 in a military operation to force them from their villages.
Kurds, whose northern region is still haunted by the seven-month "Anfal" campaign, have long sought justice and want the former president to face the death penalty.
Chief prosecutor Jaafar al-Moussawi said seven defendants including Saddam's cousin, Ali Hassan al-Majid or "Chemical Ali," would stand trial in the new case.
All seven face charges of war crimes and crimes against humanity.
Saddam and Majid face the additional graver charge of genocide, which also carries the death penalty.
Saddam is currently being tried only for crimes against humanity.
"Anfal," meaning "spoils of war," is a term taken from a verse in the Koran that calls for terror to be struck into the hearts of unbelievers.
Mustard gas and nerve agents were used to drive villagers from their homes.
The campaign devastated Kurdistan, a mountainous region bordering Turkey. By some estimates 4,500 villages were destroyed and hundreds of thousands of people killed, tortured or displaced.
Many were shot and their bodies dumped in mass graves.
US military investigators said this week that in two of the graves they excavated they found 123 bodies, including 88 children and infants. All had been shot in the back of the head.
