BAGHDAD, Iraq (CNN) -- Insurgents and U.S. troops battled across Iraq as talk of Shiite peace moves competed with sounds of mortars and gunfire in Najaf, the stronghold of Shiite cleric Muqtada al-Sadr and his Mehdi Army militia.
The death count over the last 24 hours was high for insurgents: 21 in the Baghdad area, 16 near Amarah, and four in Karbala, where coalition troops and the Mehdi militia have been fighting for the last four days, coalition officials said Saturday.
In the northern city of Mosul, a mortar or a rocket-propelled grenade struck a line of Iraqi civilians lined up outside an army recruitment center, killing four recruits and wounding 15 others.
Five U.S. soldiers have died in the past 24 hours -- three in separate attacks Friday, one in a vehicle accident shortly after midnight, and another from natural causes, according to coalition news releases issued Saturday.
The deaths brought to 782 the number of U.S. forces killed in the Iraq war, 643 of them since President Bush declared the end of major hostilities on May 1, 2003. Five hundred seventy of the U.S. deaths have come in hostile actions, 460 of those since May 1, 2003.
In his Saturday radio address, President Bush restated his resolve on Iraq, saying, "We must confront the enemy and stay on the offensive until these killers are defeated." (Full story)
Coalition officials have predicted an increase in insurgent attacks as the June 30 sovereignty handover approaches. U.N. special envoy Lakhdar Brahimi is in the country, helping Iraqi authorities develop a caretaker government.
But the bloodshed still worries Iraqi authorities, who want the handover and elections next year to be held in a secure, peaceful environment.
U.S. Brig. Gen. Mark Kimmitt said that there has been progress in stamping out instability -- for example in Fallujah, where there has been calm since Iraqi patrols were integrated into the security force in the city -- but the battles still continue in bastions of al-Sadr support.
In Karbala, Kimmitt said that for the fourth day in a row, militia continue to attack coalition forces around a former mosque complex there. Over the last 24 hours, four enemy fighters were killed, and one coalition soldier was wounded, he said.
Coalition spokesman: Al-Sadr must face justice
In Najaf, it was relatively quiet compared with recent days. In one incident, six mortar rounds landed near the provincial governor's building. There were no casualties or damage. There was also a U.S. incursion Friday night into the cemetery, at the Imam Ali Shrine, where insurgents ambushed troops hours earlier.
The Najaf fighting persisted despite efforts over the last week by Shiite leaders and al-Sadr to reach a peace agreement. Coalition spokesmen Saturday repeated non-negotiable demands for the militia.
"Our goal has been clear for some time," said Coalition Provisional Authority spokesman Dan Senor. "Muqtada al-Sadr must face justice and he must disband and disarm his militia."
"We have been saying from the day the situation unraveled," Senor said, adding later "that is our plan."
Al-Sadr is wanted in connection with the killing of a rival cleric.
Senor and Kimmitt said they appreciate peace-making efforts by citizens.
One of the ideas floated was that the militia and U.S. troops leave the city. The coalition believes that it would stay as far out of the city as practical.
There have been hopes for a negotiated settlement. Fliers were handed out in the streets of Najaf Thursday and affixed to walls outlining an agreement between al-Sadr and other groups.
It said all parties, including al-Sadr's forces, agreed to end armed militias, dissolve the Mehdi Army and turn it into a political party, develop a security force that would include the Mehdi Army, turn over government buildings and postpone the trial of al-Sadr, wanted in connection with the killing of a cleric.
The streets of Najaf are normally bustling as pilgrims flock to Shiite holy sites, but the fighting has many businesses shuttered.
