Twin bomb blasts kill 4 in Iraq

BAGHDAD, Iraq (CNN) -- Two roadside bombs planted near a gas station in Baghdad's southeastern Amin neighborhood detonated in quick succession Wednesday morning, killing at least four people and wounding seven others, according to officials.

One police officer was killed in the blasts and three other officers were wounded, according to an official with Iraq's Interior Ministry said.

Seven people were wounded when a mortar round landed on the Ibn al-Nafis Hospital in central Baghdad, just before midday, the ministry said.

In another attack, a pair of mortars landed on a residential area in southwestern Baghdad's Sada district, killing two people and wounding five others.

Meanwhile, three U.S. soldiers were killed by roadside bombs while fighting in the Iraqi capital Tuesday, U.S. military statements released Wednesday said.

One soldier was killed by a roadside bomb in eastern Baghdad and four other soldiers were wounded. The military said the explosion occurred while the soldiers were on patrol.

According to the statement, the troops later found two insurgents behind the attack and killed them.

Two other U.S. soldiers were killed in western Baghdad when a roadside bomb exploded near their vehicle.

With the new fatalities, the number of U.S. service members killed since the onset of the war is 3,620, according to a CNN count.

Insurgents wearing military uniforms killed 29 people in an attack early Tuesday on a village near Baquba, while a suicide car bomber struck an army patrol east of Baghdad, killing 11, the Iraqi Interior Ministry said. E-mail to a friend
