Via the NYT: U.S. Seizes Suspect in Killing of Sunni Sheik in Iraq

An American military statement announced the arrest of the suspect, Fallah Khalifa Fayyas al-Jumaili, after a raid near Balad, north of Baghdad. Mr. Jumaili, also known as Abu Khamis, had been involved in a plot to kill several Sunni leaders working with the Americans against Sunni extremists, the statement said.

The story does not indicate with whom the individual in question is affiliated (i.e., whether he is with AQI, another Sunni faction or what).
