Attacks in Iraq killed 1,506 civilians in April, a 20 percent declined compared to the previous month, Iraqi government figures indicated on Tuesday.
A U.S.-backed security crackdown in Baghdad has helped reduce some violence in the city, the report said. The figures were compiled by the interior, defense and health ministries and cited by Reuters. The number of civilians killed in March was 1,861 and 1,645 in February.
Last month, 130 Iraqi policemen and 63 Iraqi soldiers were killed, the data showed. During April, 104 American troops killed, making it one of the deadliest months since the invasion in 2003.
The Iraqi data showed nearly 3,000 "militants" were arrested during the month.
Meanwhile, the State Department said Monday that 13,340 of people were killed in terrorist attack in Iraq during 2006. It said in Iraq, the use of chemical weapons, seen for the first time in a Nov. 23, 2006, attack in Sadr City, also "signaled a dangerous strategic shift in tactics."
