Mohamed al-Sumaidaie, Iraq's ambassador to the United Nations, accused U.S. marines of murdering his cousin's 21-year-old son, Mohammed Sumaidaie, who was studying engineering at the University of Technology in Baghdad. "All indications point to a killing of an unarmed innocent civilian - a cold-blooded murder," said Sumaidaie. "The Marines were smiling at each other as they were leaving.".
The murdered was an engineer student.
