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. Eleven Americans were wounded, the U.S. military said. Such intense resistance often suggests an attempt to defend a high-value target.

Family members of Jordanian-born Abu Musab al-Zarqawi renounced the terrorist leader Sunday after his al-Qaida in
Iraq group claimed responsibility for the Nov. 9 suicide attacks on three Amman hotels that killed 59 people.

The family of al-Zarqawi, whose real name is Ahmed Fadheel Nazzal al-Khalayleh, reiterated their strong allegiance to Jordan's King Abdullah II in half-page advertisements in the kingdom's three main newspapers. Al-Zarqawi threatened to kill the king in an audiotape released Friday.

"A Jordanian doesn't stab himself with his own spear," said the statement by 57 members of the al-Khalayleh family, including al-Zarqawi's brother and cousin. "We sever links with him until doomsday."

The statement is a serious blow to al-Zarqawi, who no longer will enjoy the protection of his tribe and whose family members may seek to kill him.

"As we pledge to maintain homage to your throne and to our precious Jordan ... we denounce in the clearest terms all the terrorist actions claimed by the so-called Ahmed Fadheel Nazzal al-Khalayleh, who calls himself Abu Musab al-Zarqawi," the family members said.

Sajida Mubarak Atrous al-Rishawi was not able to detonate her bomb at the wedding party and fled with the guests as her husband exploded himself. Now, she is in the custody of the GID, Jordan’s intelligence agency. By all accounts, the interrogation is going slowly. Still, enough information is emerging for us to draw some lessons for the triple bombings in Amman, Jordan, on November 9.

Mrs. al-Rishawi’s family history reveals just how effective the U.S. military has proven to be in eliminating insurgents. Jordanian intelligence has learned that three of her brothers were killed by coalition forces in Iraq. Her brother, Thamir al-Rashawi, a member al-Zarqawi’s inner circle, was killed in April 2004 in Fallujah, when a missile fired from a U.S. aircraft struck his pick-up truck. Jordanian Deputy Prime Minister Marwan al-Mu’ashir described her brother, Thamir, as “the emir [commander] of the Al-Anbar region [of the Iraqi insurgency] in the Al-Qa’idah of Jihad Organization in the Land of Two Rivers. He was the right hand of Abu-Mus’ab al-Zarqawi.”

Her other two brothers, Ammar and Yassir, died in separate battles with U.S. forces in Ramadi, Iraq, in 2005.
