BAGHDAD, Iraq — A roadside bombing killed four U.S. soldiers in southwestern Baghdad, the U.S. command said yesterday.

A statement by the U.S. command said the soldiers from Task Force Baghdad died Sunday night when their vehicle ran over a roadside bomb in the southwest of the city. The statement gave no further details.

However, Jim Driscoll, a spokesman for the Georgia National Guard, said the victims were assigned to the 48th Infantry Brigade.

They were the Georgia Guard unit's first combat casualties since World War II.

At least 1,782 members of the U.S. military have died since the Iraq war began in March 2003, according to an Associated Press count.
