NAJAF, Iraq (CNN) -- Combat operations in Najaf were temporarily suspended late Friday to allow political negotiations with radical Shiite cleric Muqtada al-Sadr to go forward, U.S. military officials reported.
A high-level delegation from the interim Iraqi government is expected to arrive in Najaf overnight, officials said.
The delegation will try to meet with al-Sadr in an effort to bring a peaceful end to the tense standoff around the Imam Ali mosque, one of the holiest shrines in Shiite Islam.
Earlier Friday, Iraqi Interior Ministry spokesman Sabah Kadhim said Iraqi police seized control of the mosque. But later, Iraqi police said they had not.
There have been no signs of activity around the mosque all day Friday, according to CNN producer Kianne Sadeq, who is nearby.
U.S. officials at the Pentagon said there is no sense that supporters of al-Sadr have pulled out of the mosque; and that U.S. and Iraqi forces still surround it.
A senior aide to al-Sadr said the Medhi Army has not yet handed over the keys to the mosque since no high religious authority has been found to take them.
U.S. and Iraqi forces surrounded the mosque in an effort to pressure al-Sadr's fighters, who were holed up in the complex.
Meanwhile, Iraqi Ministry of Health officials said 77 Iraqis were killed and 70 were wounded overnight in heavy fighting.
The dead included six Iraqi police officers.
Recent fighting in the city center has damaged the mosque and two of its minarets, according to CNN's Sadeq.
Al-Sadr has refused to negotiate on the latest Iraqi government ultimatum because, an aide said, he and his forces want to deal with a delegation from the Iraqi National Conference and not one from the interim government.
At the Iraqi National Conference, more than 1,000 religious, political and civic leaders are working to elect a 100-member council to advise and oversee the interim government until elections in January.
Iraqi officials have threatened to "liberate" the mosque in a military offensive if al-Sadr's militia forces don't leave.
"We are very determined that blood loss should be minimized," interim Prime Minister Ayad Allawi said.
Sadeq, who went inside the mosque compound Thursday with a group of journalists, reported persistent sounds of mortars, gunfire and explosions. She said there was also a great deal of sniper fire.
The journalists were greeted by the Mehdi Army with cheers and chants of "We will not stand down!" Fighters flashed pictures of al-Sadr and many danced. Also inside the compound were women and children, most of whom appeared in a festive mood like the rest of the al-Sadr followers. (On the Scene: Inside the mosque)
Airstrikes in Falluja
U.S. airstrikes on antiaircraft positions in Falluja on Friday killed at least five Iraqis, according to a hospital official in the city.
Lt. Col. Thomas Johnson with the 1st Marine Expeditionary Force said the airstrikes targeted sites that were firing on U.S. aircraft.
The first strike happened around 1 a.m. (5 p.m. Thursday ET) in the western district of al-Sina'i, killing two people and wounding four others.
The second took place about 10 hours later and resulted in large secondary explosions, Johnson said, suggesting a weapons depot was near the antiaircraft position.
A Falluja hospital official said the airstrike hit a milk factory, killing three Iraqis and wounding two others.
Earlier, a U.S. C-130 gunship fired on insurgents in eastern Falluja, after insurgents fired small arms and antiaircraft weapons at the gunship overnight Thursday. They were also seen firing mortars at a U.S. military base there.
