US forces arrested six men linked to last week's slaying of Baghdad Governor Ali al-Hadaeri, the US military said today. "An early morning raid on January 11 netted ... six possible insurgents suspected of involvement in the assassination of the governor of Baghdad province," the army said in a statement. US Major Web Wright said the arrests indicated US forces were gleaning better intelligence from locals. Three other people were also killed in the carefully planned January 4 ambush of Hadaeri, the highest-ranking Iraqi official to be assassinated since last July, when his Mosul counterpart was killed. His assassination was followed by that on Monday of Baghdad's deputy police chief and his son.
