Five U.S. soldiers were killed and six others injured in insurgent attacks in Baghdad and western Iraq, the U.S. military said on Tuesday.

A soldier assigned to Multi-National Division - Baghdad was killed and two others injured along with their Iraqi interpreter when a sophisticated armored-piercing roadside bomb detonated near their vehicle in southern Baghdad on Monday, the U.S. military said in a statement.

"The unit was conducting a combat security patrol at the time of the attack," it said.

The explosively formed projectiles, or EFPs, were allegedly come from Iran, according to U.S. officials, who previously accused the neighboring country of providing Iraqi Shiite militias with weapons and parts for such bombs.

A second soldier assigned to the same unit was killed and one more wounded when a roadside bomb went off near their vehicle while conducting a security patrol in southern Baghdad on Monday, the military said in another statement.

Another soldier was killed and one more injured when insurgents attacked their vehicle with small arms fire while conducting combat security patrol in southwestern the capital on Monday, the military said in a statement.

Two soldiers were killed and two others injured when their M-1114 vehicle was hit by a roadside bomb in the restive city of Fallujah, 50 km west of Baghdad, on Saturday, according to a separate statement.

Names of the soldiers are being withheld pending notification of next-of-kin and release by the U.S. Department of Defense, the statements said.

About 3,310 U.S. soldiers have been killed in Iraq since the U. S.-led invasion in March 2003, according to media count based on Pentagon figures.
