It has been 20 years since the start of the Iraq War.
On 16 September 2007, private security guards employed by the American firm Blackwater opened fire on civilians in Baghdad's Nisour Square. Seventeen Iraqis were killed, and another 20 injured.
The Blackwater guards, who were escorting a convoy from the American embassy, claimed that they had come under attack from insurgents, but eye-witnesses and Iraqi officials quickly dismissed that version of events.
Mohammed Kinani's nine year old son, Ali, was one of the victims.
In this programme, first broadcast in 2020, Mohammed shares his story with Mike Lanchin.
