A United States general has said that American forces had no role in the execution of Saddam Hussein last Saturday, but would have handled it differently.
Speaking at a news conference, Major General William Caldwell said security measures, including searches for mobile phones, were left to the Iraqis.
Earlier, a senior Iraqi official said a security guard at the execution has been arrested in connection with the investigation into the recording and distributed of phone camera footage of the execution.
The Iraqi government began the inquiry in an effort to calm anger among Sunnis which has led to thousands of protestors taking to the streets.
A three-man panel has been appointed to investigate the matter. A spokesman said what happened did not reflect the views of the authorities.
In the unofficial footage, which included audio, some of those attending the execution were heard bitterly taunting the former Iraqi president as he stood on the gallows, moments from death.
Reports: Saddam's half brother to be executed tomorrow
Reports from Iraq today say the authorities will execute Saddam Hussein's half brother, Barzan al-Tikriti, and a former chief judge, Arwad al-Banda, tomorrow.
They were found guilty along with Saddam of crimes against humanity over the killing of more than 150 Shias in the town of Dujail in the 1980s.
Death sentences for al-Qaeda related terrorist offences
An Iraqi court has sentenced a Saudi, a Syrian and a Sudanese to death after finding them guilty of al-Qaeda related terrorist offences, the US-led coalition in Iraq confirmed this morning.
The alleged foreign fighters were among 48 detainees convicted by the Central Criminal Court of Iraq between 8 and 28 December last year.
Since the fall of Saddam Hussein's government in March 2003, hundreds of Muslim volunteers have flooded into Iraq to fight against US forces.
