The U.S. military says an American soldier has been killed during operations in southern Iraq.
The soldier died Wednesday, but was not identified because family had not been notified. Other details also were withheld.
The death brings to 4,460 the number of American service members who have died in Iraq since the war began in 2003, according to an Associated Press count. Five other American soldiers died earlier this week in a rocket attack on a base in Baghdad.
Shiite Muslim militias have stepped up attacks on U.S. forces with the approach of the year-end withdrawal of all American troops.
