BAGHDAD, Iraq (CNN) -- Iraqi Prime Minister Nuri al-Maliki told neighboring countries Tuesday that Iraq has moved past its internal divisions and "has entered a new phase" of unity.
U.S. soldiers stand guard Tuesday outside an entrance to Baghdad's Sadr City neighborhood.
The rosy declaration comes amid a growing confrontation with a radical Shiite cleric and his followers.
"Iraq has passed its crises and divisions," al-Maliki told diplomats meeting in Kuwait at the third expanded neighbors conference.
"The will of all its people is united, and it's moving forward to develop the political process," he said. "It has entered a new phase, where the interest of the country transcends differences."
U.S. Secretary of State Condoleezza Rice is also attending the conference, along with 29 foreign ministers and other top world body representatives.
Rice said she hopes to rally more support among Iraq's neighbors to help reinforce Iraq's recent successes.
Al-Maliki pressed his neighbors to stand by their pledges to forgive Iraq's past debts and set up diplomatic missions in Baghdad. Kuwaiti Foreign Minister Mohammed al-Sabah said the next expanded neighbors conference will be held in Baghdad.
On Monday, Sadrist lawmaker Nassar al-Rubaie said al-Sadr's movement is "ready for all options" after the rival parties that dominate Iraq's government failed to meet conditions under a recent cease-fire.
On Saturday, al-Sadr issued what he called a "last warning" to the government and told his followers to fight the "occupier" in his Baghdad stronghold of Sadr City.
The latest round of fighting between U.S.-backed Iraqi forces and fighters loyal to al-Sadr left two dead and three wounded Tuesday, an Interior Ministry official said.
Also on Tuesday, an Interior Ministry official said a U.S. airstrike in Sadr City killed 10 people and wounded 17. But the U.S. military called it a precision strike on a vehicle in which no civilians were killed or injured.
A U.S. military statement said the vehicle that was destroyed was leaving a "point of origin" after a mortar attack. People were seen getting into the vehicle and then driving away after loading a mortar tube into the vehicle's trunk.
After two people were dropped off, the driver continued before stopping the vehicle, getting out and walking away, the statement said. An airstrike at that time was not possible due to civilians in the area, the statement added.
Once the area was cleared, the U.S. military said, one Hellfire missile was launched at the vehicle. Civilians then rushed to the car and appeared to grab the mortar tube out of the trunk and throw it into another vehicle that drove away, the military said.
U.S. Lt. Col. Steve Stover described several other incidents in other parts of Baghdad. He said that more than 12 hours before the Sadr City blast, in an area near Sadr City called New Baghdad, a airstrike killed a man seen laying wire for a roadside bomb.
Stover also said that on Tuesday afternoon, an Iraqi army patrol was hit by a roadside bomb in the Mansour neighborhood, wounding five soldiers and 16 civilians.
U.S. troops killed another man caught running a wire for a roadside bomb and arrested three others suspected of setting another roadside bomb, both incidents occurring in New Baghdad, he said.
In his address Tuesday, al-Maliki cited Basra as one example of Iraq's recent successes.
"We have made noticeable progress in securing Baghdad where the security plan succeeded and life returned to normal in Anbar province after it was cleaned up of al Qaeda gangs," he said.
"We were able to impose the government's authority and pursue outlaws in Basra and other provinces, and Nineveh will witness an operation to cleanse it of al Qaeda gangs and remnants of the former regime."
The prime minister called on his country's neighbors to take the "serious big steps" to implement the decisions made at previous conferences.
"A stable and safe Iraq will be in the interest of regional countries and the world," al-Maliki said.
At a news conference with his Kuwaiti counterpart, Iraqi Foreign Minister Hoshyar Zebari said, "We are not expecting miracles" from the conference in Kuwait.
