In one incident, a soldier was killed and three were wounded in a roadside bombing in Fallujah, 30 miles west of Baghdad. The military said the attack occurred at 7:10 a.m. The dead soldier was from the 3rd Armored Cavalry Regiment, the military said. It provided no other details.

The second death came in an attack on a military convoy at 7:45 a.m. in Baghdad. The dead soldier was of the 205th Military Intelligence Brigade. No other details were given.

The deaths brought to 281 the number of soldiers killed since the war began on March 20. Since President Bush declared major combat over on May 1, 143 American soldiers have died.

Meanwhile, the military has announced some Fort Lewis soldiers were injured when their truck hit a mine outside Tikrit, about 120 miles north of Baghdad.

The six soldiers were taken to a military hospital in Landstuhl, Germany, Army spokesman Lt. Col. Stephen Barger told The News Tribune. Identities and conditions were not released Tuesday.

All are members of the 555th Combat Engineer Group, 14th Engineer Battalion, which specializes in setting and clearing mine fields, breaching obstacles and demolitions.

The six were injured Friday while traveling north of Tikrit, said Barger.

The wounded soldiers were treated at the 28th Combat Support Hospital, Barger said, then flown to Landstuhl for further evaluation.

Additional information regarding the incident was unavailable from the Department of Defense or the U.S. Central Command in Florida.

More than 500 soldiers from the 14th Engineer Battalion were deployed to Iraq in April.

The division has upgraded security in areas where they are staying. They've also built walls, bunkers, guard towers and concrete pads for satellite dishes.
