Followers of the rebel Shia cleric Moqtada Sadr are still in control of the Imam Ali shrine in Iraq.
Iraqi officials said on Friday that police had entered the mosque and taken control of the area.
But reporters in Najaf say there are about 1,000 unarmed Sadr supporters still inside the building.
Armed fighters have also been seen covering defending positions outside the shrine and are surrounded by US tanks and armoured vehicles.
Nobody seems to know were Moqtada Sadr is.
