Iraqi security officials say car bombings and roadside explosions across Baghdad Tuesday killed at least 37 people and wounded many more.
Medical officials say a car bomb killed at least 15 people near a mosque in a Sunni neighborhood of the capital.
Earlier Tuesday, three near simultaneous car bombs exploded in western Baghdad, killing at least 16. Other attacks took place in central and eastern parts of the city.
Iraqi police also say they found the bodies of 40 victims of apparent sectarian violence in Baghdad Monday. Many showed signs of torture.
Meanwhile, the U.S. military announced the deaths of six more American soldiers. This raises the U.S. death toll in Iraq to nearly 3,000 (2,978).
That is more than the number of people killed in the September 11 attacks on the U.S.
The military also says coalition forces captured a "suspected leader of a murder and kidnapping cell" near Baghdad.
