BAGHDAD - Four al-Qaida-linked detainees have escaped from a Baghdad area prison that was handed over by the US to Iraqi authorities a week ago, Iraq's justice minister said Thursday.
Dara Noureddin said the four, awaiting trial on terrorism charges, escaped from the prison formerly known as Camp Cropper.
The handover of the facility marked a milestone for Iraq's push to regain full sovereignty as the US pulls out the last of its combat forces by the end of next month.
The US military could not immediately be reached for comment.
Noureddin did not name the men who escaped, but said they had been arrested by US forces in 2008 in western Iraq.
"The four detainees were awaiting trial after their arrest" on terrorism charges, Noureddin said.
Two Iraqi intelligence officials and a third in the Interior Ministry who are knowledgeable about the case said authorities believe the four men -- whom they identified as al-Qaida members -- were aided by the man in charge of their prison block.
The intelligence officials said the four were discovered missing Tuesday during an evening roll call. When prison staff went to inform the unit head, they found that he, too, was missing. He has not reported for work since, they said.
The intelligence officials said one of the escapees is believed to be a senior member of the group, and had the title of finance minister of the Islamic State of Iraq, an al-Qaida front group.
All three officials spoke on condition of anonymity because they were not authorized to release the details of the investigation to the media.
The US forces handed over about 1,500 prisoners to Iraqi authorities July 15, but continue to hold 200 detainees at the request of the Iraqi government. They are kept in a separate part of the prison dubbed Compound 5.
