A U.S. official said Sunday that efforts were under way to determine if terror leader Abu Musab al-Zarqawi was among the dead. Insurgents, meanwhile, killed an American soldier and a Marine in separate attacks over the weekend, while a British soldier was killed by a roadside bomb in the south. In Washington, a U.S. official said the identities of the terror suspects killed in the Saturday raid was unknown. Asked if they could include al-Zarqawi, the official replied: "There are efforts under way to determine if he was killed." The official spoke on condition of anonymity because of the sensitivity of the information. On Saturday, police Brig. Gen. Said Ahmed al-Jubouri said the raid was launched after a tip that top al-Qaida operatives, possibly including al-Zarqawi, were in the house in the northeastern part of the city.
