Roadside bomb kills U.S. soldier near Baghdad

Two Marines and a U.S. sailor were killed Sunday.
BAGHDAD, Iraq (AP) -- A roadside bomb killed a U.S. soldier north of Baghdad on Monday, and the American military announced the capture of two alleged death squad leaders as U.S. and Iraqi authorities step up efforts to stem rampant sectarian violence.
President Bush, meanwhile, served notice that he would not change course or flinch from debate about the unpopular war in Iraq as he campaigns for Republicans in the fall congressional elections. In fact, he suggested that national security and the economy should be the top political issues, and criticized the Democrats' approach on both.
Many Democrats want to leave Iraq "before the job is done," Bush told reporters in Washington.
"I can't tell you exactly when it's going to be done," he said, but "if we ever give up the desire to help people who live in freedom, we will have lost our soul as a nation, as far as I'm concerned," he added.
Death squads
The two men accused of leading death squads were captured Sunday in southern Baghdad during simultaneous raids.
Both suspects "exercise control over all death squad cell activity" in the Sunni districts of Dora and Sahha and the predominantly Shiite Abu D'Shair in Baghdad, the military said in a statement.
It also accused one of the men of torturing and killing Iraqis in a Shiite mosque in the capital, although no details were provided. Four other suspicious individuals were detained during the operation, it said.
Some 12,000 U.S. and Iraqi forces are being deployed in the capital as part of a security crackdown on a surge of insurgent attacks and sectarian bloodshed.
A separate military statement said a U.S. soldier died Monday when the vehicle in which he was riding was struck by a roadside bomb.
The death came a day after two Marines and a sailor, assigned to the Regimental Combat Team 7, died in fighting in the province of Anbar, the stronghold of the Sunni Arab insurgency west of Baghdad.
At least 2,610 members of the U.S. military have died since the Iraq war started in March 2003, according to an Associated Press count.
Violence
In other violence, a person was shot to death in the northern city of Mosul.
But Iraqis generally enjoyed a rare day of relative peace as they returned to Baghdad's streets after a weekend vehicle ban during a Shiite religious commemoration that was disrupted by sniper attacks on pilgrims in another episode of sectarian bloodletting.
The Iraqi government said 20 people were killed by snipers who hid in buildings and sprayed bullets into Shiite religious processions Sunday. The U.S. military, however, said only five people were killed. The discrepancy in the toll could not be immediately reconciled.
Prime Minister Nouri al-Maliki, a Shiite, thanked the armed forces for preventing major attacks. "We condemn strongly the terrorists attacks committed by the terrorists against innocent civilians," he said in a statement.
