Amateur footage recently posted on the internet shows American troops firing live ammunition on Iraqi prisoners during a riot in a US detention facility in Iraq back in 2005.
The footage shows US forces using disproportionate force and live rounds against prisoners at the US prison facility Camp Bucca located in Iraq.
The Iraqi detainees were protesting the American troops' desecration of Islam's holy book, the Qur'an.
At the time, the US military tried to cover up the bloodshed, saying the riot happened when the prisoners confronted a search for contraband in the prison.
But the American Civil Liberties Union (ACLU) later revealed that the real cause of the riot was the desecration of the Holy Qur'an by US troops.
Four prisoners were shot dead and five others wounded during the violence.
In 2008, the US military revealed that it held a total of around 20,000 detainees, some 17,000 of whom at Camp Bucca near Basra in southern Iraq, and more than 3,000 others at Camp Cropper in the capital Baghdad.
