BAGHDAD (AP) - A top Iraqi official confirms that Iraq is holding four former detainees from the Guantanamo detention facility to see whether they pose a threat.

Acting Justice Minister Safaaulddin al-Safi tells The Associated Press that a judge has approved their continued detention for two weeks while authorities interrogate and investigate them.

The four were arrested in Afghanistan and held at Guantanamo before being handed over to the Iraqis last month.

Al-Safi says the four are not wanted for crimes in Iraq but authorities want to make sure they pose no threat if set free.

President Barack Obama has ordered the detention center in Cuba to be closed within a year as part of his overhaul of U.S. national security policy.
