(CBS/AP) The killings of three U.S. soldiers in separate attacks in Baghdad pushed the American death toll for April up to 47, making it the deadliest month since September.
One soldier died when his vehicle was struck by a roadside bomb. The other died of wounds sustained when he was attacked by small-arms fire, the military said Wednesday. Both incidents occurred Tuesday in northwestern Baghdad.
A third soldier died in a roadside bombing Tuesday night in the east of the capital, the military said.
The statement did not give a more specific location. But the eastern half of Baghdad includes embattled Sadr City and other neighborhoods that have been the focus of intense combat between Shiite militants and U.S.-Iraqi troops for more than a month.
In all, at least 4,059 members of the U.S. military have died since the Iraq war started in March 2003, according to an Associated Press count.
"We have said all along that this will be a tough fight and there will be periods where we see these extremists, these criminal groups and al Qaeda terrorists seek to reassert themselves," U.S. military spokesman Maj. Gen. Kevin Bergner told reporters in Baghdad.
"So, the sacrifice of our troopers, the sacrifice of Iraqi forces and Iraqi citizens reflects this challenge," Bergner said in response to a question about what's behind the increase in American troop deaths.
The latest fighting erupted at the end of March after Prime Minister Nouri al-Maliki launched a crackdown against Shiite militias in the southern port city of Basra. But it quickly spread to Baghdad's Sadr City, a sprawling slum with about 2.5 million people that is a stronghold of the Mahdi Army militia of anti-American cleric Muqtada al-Sadr.
The militiamen have used the district as a base to fire barrages of missiles and mortar rounds at the U.S.-protected Green Zone which houses much of the Iraqi government and Western diplomatic missions, including the U.S. and British embassies.
They also have fought running street battles in which hundreds have died. The U.S. military says those killed have been mainly gunmen. But police and medical authorities in Sadr City say innocent civilians have frequently gotten caught up in the fighting.
Such street battles - in tight confines and amid frightened civilians - are increasingly becoming a hallmark of the drive into Sadr City and recall the type of head-on clashes last seen in large numbers during last year's U.S. troop buildup in Baghdad and surrounding areas.
Tahseen al-Sheikhly, the spokesman for the civilian side of Baghdad security operations, said Wednesday that a total of 925 people had died and 2,605 were wounded in Sadr City. But he gave no timeframe or details about how the figure was reached.
Previous Interior Ministry casualty figures for the past month had indicated that less than 400 people had perished. It was not immediately possible to reconcile the conflicting figures. Officials at the Baghdad military operations center said they could not confirm al-Sheikhly's count.
The Sadr City violence continued overnight with the destruction of a school in the district. AP Television News footage showed that parts of the two-floor Baghdad Girls' School had pancaked as the result of an explosion. Desks were hanging down from the slanting classrooms where the outer walls were blown out by the blast.
Local officials said the school was the target of an airstrike on Tuesday evening.
An official at the local hospital, who asked not to be named because he was not authorized to release the information, said two people were killed and 16 wounded overnight in Sadr City. He said this brought the death toll in the district since Tuesday to 31, with 107 wounded.
The U.S. military had no comment about the school but said an Abrams tank fired a 120 mm shell at gunmen shooting at U.S. troops in Sadr City, killing all three. In another part of Sadr City, an unmanned drone fired a missile at a group of men planting a roadside bomb and killed one, the military said.
On Wednesday, al-Maliki accused the Mahdi Army of using civilians as human shields, and vowed to continue the crackdown against militias.
"We can't build a state along with militias," he told reporters at a news conference. "We want to build a single national army."
Al-Maliki said gunmen had killed the nephew of police Maj. Gen. Abdul-Karim Khalaf, an Interior Ministry spokesman who had also overseen operations in Basra, by hanging him from an electricity pole in Sadr City.

White House officials this week privately cautioned lawmakers not to go too far in restricting U.S. aid to Iraq, warning that doing so might only prolong the war, now in its sixth year. In the meantime, independent investigators conclude in a report that substantial U.S. support continues despite Baghdad's anticipated $70 billion windfall in oil revenues.
The Pentagon released the identity of a U.S. service member who was killed in Iraq on Monday. Spc. David P. McCormick, 26, of Fresno, Texas, died April 28 in Baghdad from wounds suffered in a rocket attack upon his forward operating base. He was assigned to the 1st Squadron, 75th Cavalry Regiment, 2nd Brigade Combat Team, 101st Airborne Division (Air Assault), Fort Campbell, Ky.
Also in Baghdad, a senior government official was killed in a roadside bombing in the north of the city. Dhia Jodi Jaber, director general at the Ministry of Labor and Social Affairs, was hit by a roadside bomb as he left his home, the ministry's spokesman Abdullah al-Lami said.
An Iraqi court adjourned until May 20 the trial of Tariq Aziz, one of Saddam Hussein's best-known lieutenants, and seven other defendants over charges of allegedly ordering the execution of dozens of merchants for profiteering half an hour after it started. The judge postponed the trial, saying co-defendant Ali Hassan al-Majid, Saddam Hussein's cousin who is known as "Chemical Ali," was too ill to attend.
