Marine was killed when a roadside bomb exploded near his vehicle near the troubled city of Fallujah, the military said Tuesday.
The Marine, who was part of Regimental Combat Team-8, 2nd Marine Division, was killed din action on Monday, the statement said. No further details were released.
Fallujah, 65 kilometers (40 miles) west of Baghdad, was devastated last November when the marines retook it from guerrillas. The city has been the scene of increasingly frequent clashes.
The latest death brought to at least 65 the number of American service members killed in Iraq this month, reports the AP.
According to CNN, President Bush on Saturday said the United States is fighting "terrorists in Afghanistan, Iraq, and around the world," and a former U.S. senator who fought in the Vietnam War denounced the Iraq war effort, saying "its plan for victory is not working."
Bush delivered his remarks in his weekly radio address and former U.S. Sen. Max Cleland of Georgia spoke in the weekly Democratic radio response.
Their words reflect the different priorities of Americans concerning the war in Iraq, which the United States launched more than two years ago, versus the conflict in Afghanistan, which began a month after al Qaeda attacked the United States on September 11, 2001.
"Our troops know that they're fighting in Iraq, Afghanistan, and elsewhere to protect their fellow Americans from a savage enemy.”
"They know that if we do not confront these evil men abroad, we will have to face them one day in our own cities and streets, and they know that the safety and security of every American is at stake in this war, and they know we will prevail," Bush said.
