It said US forces suffered no casualties, but a teenager was killed and a pregnant woman wounded in one of the clashes.
The raids come after a bombing campaign in Baghdad on Thursday that killed more than 200 Shia.
Earlier on Saturday, the bodies of 21 Iraqi villagers from two families abducted and killed by gunmen overnight were found in the Diyala province northeast of the capital.
Police said armed men attacked the families, who were from a Shia tribe, late on Friday night in Imam Mansour village, near the town of Balad Ruz, and dragged out all the men.
Their corpses were found on Saturday morning, shot execution-style.
