BAGHDAD, Iraq (CNN) -- A suicide car bombing near a car dealership killed 11 Iraqis and wounded 36 in the northern city of Tal Afar, the Interior Ministry said Saturday.
Iraqis pass blown-up vehicles after a roadside bomb went off as police drove past in Baghdad on Saturday.
The U.S. military said attackers targeted civilians.
The U.S. put the death toll at nine and said 40 people were wounded.
Tal Afar is about 43 miles (70 kilometers) west of Mosul.
In Baghdad, at least three people were killed and 23 others wounded when a bomb detonated Saturday evening in a parked car in a busy area of central Baghdad's Karrada district, a ministry official said. A dozen cars were destroyed, the official said.
Earlier Saturday, a roadside bombing targeting a police patrol in northern Baghdad wounded at least seven people. Three of the injured were police officers, and the other four were civilians.
Also, a bomb attached to an empty oil tanker detonated Saturday morning in eastern Baghdad, wounding three civilians, the ministry said.
In Mosul, two U.S. soldiers were killed Saturday in a helicopter hard landing, the U.S. military said in a statement.
Their names were withheld pending notification of relatives.
The incident did not appear to be combat-related, the military said in a written statement, and there was no enemy contact in the area.
Earlier, the U.S. military said coalition forces reported that an OH-58 Kiowa Warrior helicopter made a hard landing about 6:20 p.m. local time after it came into contact with wires.
