The long-awaited transfer of the U.S. detention center in Afghanistan has been delayed once again as a deal struck between the two governments broke down the day before a planned handover ceremony, The Associated Press reported.

As recently as Friday, March 8 morning, Afghan workers at the Defense Ministry were arranging transport for dignitaries and journalists to attend Saturday's ceremony at the detention center adjoining the Bagram Air Field, a U.S. base about an hour outside of the capital.

Then on Saturday morning, organizers told journalists that the ceremony had been canceled. Afghan officials declined to give a reason for the cancellation.

U.S. forces spokesman Jamie Graybeal says details of the transfer still needed to be worked out and a full agreement has not been reached.
