Al-Sadr's Mahdi Army had appeared poised to vacate the Imam Ali shrine on Friday after agreeing to give up its keys.
But by Saturday morning, aides to both al-Sadr and Iraq's top Shia leader, Grand Ayatollah Ali al-Husseini al-Sistan were still negotiating the details of a handover.
A spokesperson for al-Sadr, Sheikh Ahmed al Shabani, said a transfer would not be completed until an inventory is taken of the shrine's contents.
Another spokesperson, Sheik Ali Smeism, said the militants wanted a delegation from al-Sistani's office to inspect the shrine and make sure its treasures were intact.
The shrine has been the focal point of a 16-day standoff between the Mahdi Army militia that supports al-Sadr, and U.S. and Iraqi forces that surround the southern Iraqi city.
