President Bush on Thursday promised to disclose the results of an investigation into reports that Marines killed unarmed civilians in Iraq. "The world will see the full and complete investigation," Bush said.

The U.S. military is conducting at least two investigations into the Nov. 19 killings of 24 people in Haditha, including women and children, following a bomb attack on a military convoy in which a Marine died. The Iraqi government is doing a separate investigation.

"If there is a wrongdoing, people will be held to account," Bush told reporters after a Cabinet meeting at the White House.

The president said the ethical training ordered for U.S. troops in Iraq following reports that Marines killed unarmed civilians will serve as a reminder of the international rules of war.

"This is just a reminder — for troops in Iraq or throughout our military — that there are high standards expected of them and that there are strong rules of engagement," said Bush, who said he has spoken to Marine Gen. Peter Pace, chairman of the military's Joint Chiefs of Staff, about the matter several times.

"At the same time what you're seeing is the Marine Corps reminding our troops about what it means to be a Marine — what it means to uphold the honor of that corps, and what it means to adhere to the rules of engagement that we expect our soldiers to adhere to."
