An Iraqi militant group posted on the Internet on Monday a video it said showed the killing of a U.S. security consultant it had abducted earlier this month. The Islamic Army in Iraq had announced on Dec. 8 that it had killed the man, identified as Ronald Schultz, because the U.S. government had not fulfilled its demands, which included freeing all Iraqi prisoners and compensation for Iraqi families. The brief video showed a gunman repeatedly shooting an automatic weapon at a blindfolded man who was kneeling on the ground. It did not show his face, Reuters reported.
