We've seen on the news the horrific scenes at mass graves in Iraq where the victims of Saddam Hussein's regime were buried. It's now believed there are 50 sites and some 300,000 people thought to have met their end in this way.
There have been concerns about the way the Iraqi's allowed relatives near the sites, worries that any forensic evidence needed for the future proseution of war crimes may have been contaminated.

Professor Cox joins Jenni to talk about her team's work there.
