PORTLAND (AP) — A Marine from Oregon was among the 10 Marines killed in a roadside bomb attack in Iraq that was one of the deadliest attacks against American troops in the past four months (see story, Page A8).

John Holmason, 21, of Scappoose was among those killed in an ambush Thursday near Fallujah against Marines from Regimental Combat Team 8, based at Camp Lejeune, N.C., his stepmother, Paula Holmason, told The Associated Press on Friday.

The Department of Defense had not yet released the names of those killed by Friday.

Word of the death first came from the Spotlight newspaper, which serves Scappoose, according to KGW-TV in Portland.

Eric Viuhkola, the vice principal at Scappoose High School, said Holmason graduated in 2002.
