The body of an Associated Press employee was found shot in the back of the head Friday, six days after he was last seen by his family leaving for work. Ahmed Hadi Naji, 28, was the fourth AP staffer to die violently in the Iraq war and the second AP employee killed in less than a month. He had been a messenger and occasional cameraman for the AP for 2 1/2 years. "All of us at AP share the pain and grief being felt by Ahmed's family and friends," said AP President and CEO Tom Curley. "The situation for our journalists in Iraq is unprecedented in AP's 161-year history of covering wars and conflicts. The courage of our Iraqi colleagues and their dedication to the story stand as an example to the world of journalism's enduring value."
