The mother of one of Danny Fitzsimon's victims has said she believes G4S is to blame for deciding to hire, and for arming, her son's killer.
Both Fitzsimons and her son Paul McGuigan were working for the private security firm ArmourGroup, which is owned by G4S, at the time of the incident.
Corinne Boyd-Russell says that Fitzsimons should not have been hired given his history of post-traumatic stress syndrome and the fact that he was charged with a crime in the UK.
A British security guard who shot dead two colleagues in Iraq in 2009 claims he was framed for the murders.
On one thing is agreed - Danny Fitzsimons should never have been allowed to work for private security contractors in Iraq.
