BAGHDAD, Iraq -- The country's most feared terrorist group warned foreign diplomats Friday to flee Iraq after announcing that it will put to death two kidnapped Moroccan Embassy employees.

The warning came in a statement posted on an extremist Web site in the name of Abu Musab al-Zarqawi's group, which also claimed responsibility for the July abduction and slaying of two envoys from Algeria and one from Egypt as well as the abduction and beheading of many foreign hostages.

"We are renewing our threat to those so-called diplomatic missions who have insisted on staying in Baghdad and have not yet realized the repercussions of such a challenge to the will of the mujahedeen," Friday's statement said.

The threat appeared to be aimed at undermining support for the U.S.-backed Iraqi government in Arab and Muslim countries. In addition to the Egyptian and Algerian diplomats, senior envoys from Pakistan and Bahrain escaped kidnapping attempts in July.

The Moroccans, driver Abderrahim Boualam and embassy staff member Abdelkrim el-Mouhafidi, disappeared Oct. 20 while driving to Baghdad from Jordan, where they had gone to pick up their paychecks.

Also Friday, the U.S. military announced that it had killed five senior al Qaeda figures during an airstrike Oct. 29 on three buildings in Husaybah, a town near the Syrian border that is a major entry point for foreign fighters and would-be suicide bombers.

Iraq was relatively quiet Friday as the majority Shiite Muslim community began celebrating the Eid al-Fitr holiday that marks the end of the holy month of Ramadan. Sunnis began the three-day holiday Thursday.

Insurgents fired mortars at an Iraqi police checkpoint near Buhriz, a Sunni Arab stronghold 35 miles northeast of Baghdad, and then stormed the position, firing from eight vehicles, police said. Six police were killed and 10 were wounded, officials said.

Five Interior Ministry commandos died when a roadside bomb exploded close to their convoy near Tuz Khormato, 130 miles north of Baghdad, police Brig. Gen. Sarhad Qadir said. Four commandos were wounded.

An American soldier from Task Force Baghdad was fatally wounded Friday when a roadside bomb exploded near his convoy in eastern Baghdad, the military said.

Elsewhere, insurgents fired a mortar round that missed an American base on the western outskirts of Baghdad but struck a home, killing a child and wounding the mother and another of her children, police 1st Lt. Ahmed Ali said.

Meanwhile, an auditing board sponsored by the United Nations recommended Friday that the United States repay as much as $208 million to the Iraqi government for contracting work in 2003 and 2004 assigned to Halliburton subsidiary Kellogg Brown & Root Inc.

The work was paid for with Iraqi oil proceeds, but the board says it was either carried out at inflated prices or done poorly. The board did not list examples of poor work.

Some of the work involved postwar fuel imports carried out by KBR that previous audits have criticized as grossly overpriced. But this is the first time that an international auditing group has suggested that the United States repay some of that money to Iraq. The group, known as the International Advisory and Monitoring Board of the Development Fund for Iraq, compiled reports from an array of Pentagon, U.S. government and private auditors for its analysis.

A spokeswoman for Halliburton, Cathy Mann, said that the questions raised in the military audits, carried out in a Pentagon office called the Defense Contract Auditing Agency, had largely focused on issues of paperwork and documentation and said nothing about the quality of the work done by KBR. The auditing board relied heavily on the Pentagon audits in drawing its conclusions.
