"Iraq's Human Rights Ministry says a Saddam Hussein-era mass grave dating to his 1991 suppression of a Shiite revolt has been unearthed in the south.
Ministry's spokesman Kamil Ameen says government teams working on an irrigation project found the grave in an agricultural area in Maysan province.
Ameen told The Associated Press Tuesday that about 20 bodies were unearthed. The irrigation project has been put on hold until the excavation is complete.
Since the 2003 U.S.-led invasion toppling Saddam's regime, mass graves have been found across Iraq.
Following Saddam's defeat in the first Gulf War, Iraq's Shiites revolted in the south, but were brutally suppressed. Hundreds of thousands are believed to have been killed."
