The marine was killed on Monday during security and stability operations, the military said in a statement on Tuesday, without giving further details.


The death took the number of US troops killed in action in Iraq since the March 2003 invasion to 1483.


US and Iraqi troops began a massive security sweep on Sunday around al-Anbar's provincial capital Ramadi, 110km west of Baghdad.


They said they had arrested 42 suspected fighters in the first days of the operation and seized several caches of weapons, including a machine gun, a complete mortar system, three grenade launchers and bomb-making material.
