An Associated Press employee has been killed in Iraq.

The 28-year-old messenger and occasional cameraman, Ahmed Hadi Naji, was found shot in the back of the head Friday, six days after
he was last seen on his way to work in Baghdad.

He's the fourth AP staffer to die violently in the Iraq war and the second AP employee killed in less than a month.

The circumstances of the slaying remain unclear. Dozens of Iraqis are found killed almost every day in Baghdad, many believed to be victims of sectarian death squads.

He leaves a wife and 4-month-old twins.
