Is al-Zarqawi dead?

The AP reports:

U.S. forces sealed off a house in the northern city of Mosul where eight suspected al-Qaida members died in a gunfight - some by their own hand to avoid capture. A U.S. official said Sunday that efforts were under way to determine if terror leader Abu Musab al-Zarqawi was among the dead....

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.

During the intense gunbattle that followed, three insurgents detonated explosives and killed themselves to avoid capture, Iraqi officials said.
