MANNHEIM, Germany, Aug 23 (AFP) - Four US soldiers accused of mistreating prisoners at the notorious Abu Ghraib jail in Iraq face a military judge in Germany on Monday, before a trial by court martial.
The four, Corporal Charles Graner, Specialist Megan Ambuhl, Staff Sergeant Ivan Frederick and Specialist Javal Davis, are accused among other charges of assault, coercion and conspiracy to mistreat inmates at the jail near Baghdad.
The humiliation of the prisoners, seen in photographs taken by some of the suspects and made public by the media in April, caused outrage and has undermined the reputation of the United States, above all in Muslim countries.
During the two-day hearing, known as an Article 39a session, a military judge could hear witnesses, take evidence and deal with procedural matters relating to the four, but nothing that touches on their guilt or innocence.
The hearing was originally due to take place in Baghdad on June 21 but was moved to Mannheim, southern Germany amid security fears.
"This is a one-time only arrangement -- all future proceedings will be held in Baghdad unless the military judge grants a venue change at a later date," the US military in Mannheim said in a statement.
Abu Ghraib prison was a potent symbol of the ruthlessness of deposed leader Saddam Hussein.
Since his removal, people accused of "anti-coalition activities" have been detained there for months at a time, often without charge, and usually only have their case reviewed every six months.
The torture scandal has seen blame pushed from a group of guards up through the military echelons. It has embarrassed US Defense Secretary Donald Rumsfeld, but has not resulted in any sackings or resignations of high-ranking officials.
The hearing in Germany follows a court procedure in the United States to determine whether Private Lynndie England, who was pictured holding a leash around the neck of a naked detainee, should face a court martial.
It has been halted so more witnesses can be called.
Attention in Mannheim will focus on Graner, who was photographed smiling, arms folded behind a hill of naked prisoners and whom England says is the father of her unborn son.
Witnesses in the hearing of England, who could face up to 38 years in jail, said that the abuses at the prison usually started in the evening when Graner was in charge of the cell block.
Her lawyer has said she has been made a scapegoat for the army and that senior officers at the jail encouraged rough treatment and abuse to soften detainees up; a defence likely to be employed by the accused in Mannheim.
