Six GIs Killed in Iraq -one a suicide?

Six U.S. soldiers have died in roadside bombings and in a shooting which may have been a suicide.

Three of the soldiers were killed in a roadside bombing late Friday north of Baghdad. Another soldier was killed Saturday also in a roadside bombing, in western Baghdad. One soldier on a patrol was killed Sunday in a blast west of Baghdad.

In a brief statement from Baghdad, the military said that another soldier was found dead Friday of a gunshot wound.

The military said an investigation was underway and did not say where the soldier was found or if an attack was suspected in the soldier's death. Many previous deaths reported in this way have subsequently turned out to have been self-inflicted.

Some 56 percent of Americans say some or all US troops should be withdrawn now.
