Suicide bomber kills 21 in northern city

At least 1,638 U.S. soldiers have died because of hostile action.
BAGHDAD, Iraq (AP) -- A suicide car bomber killed 21 people in northern Iraq on Tuesday after insurgents lured police to the scene by shooting an officer, officials said. The U.S. command said three more U.S. soldiers have been killed, pushing the American military death toll for the conflict to 2,100.
Elsewhere, insurgents fired a mortar shell at a U.S. ceremony transferring one of Saddam Hussein's palaces in Tikrit to Iraqi control. The shell failed to explode but sent the U.S. ambassador, the top American commander and robed tribal sheiks scurrying for cover as the round whistled overhead.
The suicide bomber struck on a busy commercial street in Kirkuk, a mixed Arab, Kurdish and Turkoman city in an oil-producing region 180 miles north of Baghdad. About half the dead were police who rushed to the scene after gunmen killed a fellow officer.
In addition to the 21 dead, another 24 people were wounded, according to police Brig. Gen. Sarhad Qader.
The attack was the latest in a wave of spectacular suicide operations that have killed more than 160 Iraqis since Friday. Most of the victims were Shiites.
U.S. casualties
American military casualty tolls have also been on the rise. In the latest reports, the U.S. command said a soldier was killed Monday by a roadside bomb near Habaniyah, 50 miles west of Baghdad.
Two other soldiers from Task Force Freedom were killed Saturday by small arms fire while on patrol in Mosul, 225 miles northwest of Baghdad, a U.S. statement said.
Those deaths raised the number of U.S. service members who have died since the Iraq war began in March 2003 to at least 2,100, according to an Associated Press count. At least 1,638 died as a result of hostile action, according to the military's figures.
Mortar attack
U.S. officials sought to downplay the mortar attack in Tikrit, 80 miles north of Baghdad, noting that the lone shell failed to explode or to interfere with the handover.
"This was an ineffectual attempt to stop the progress that goes on every day in Iraq," said Lt. Col. Barry Johnson, a spokesman for the U.S. command in Baghdad.
However, Arabic satellite television stations aired footage showing an American colonel ducking for cover as the shell whistled overhead. Fearing more were on the way, U.S. security hustled U.S. Ambassador Zalmay Khalilzad and the U.S. commander in Iraq, Gen. George Casey, into the palace while American infantrymen and an Apache attack helicopter searched for the source of fire. The ceremony resumed a few minutes later.
The provincial governor, Hamad Hamoud Shagtti, received a symbolic key to the palace and a deputy governor raised the Iraqi flag. Dignitaries toured the palace complex, which Saddam ordered built for his mother in 1991 and which had served as a U.S. military regional headquarters until this month.
"Although 28 other coalition operating bases have already been turned over to Iraqi Security Forces control this year, the Tikrit Palace complex is the most significant transition of real estate thus far," a U.S. statement said.
Offer to talk
In a positive development, a senior government official said a representative of an unidentified insurgent group responded to an offer by President Jalal Talabani to talk with those willing to lay down their arms.
Presidential adviser Lt. Gen. Wafiq al-Samaraei told Qatar's Al-Jazeera television that he had received a call from someone "who claimed to be a senior official of the resistance."
Also Tuesday, U.S. Marines announced the end of a major operation to secure towns along the Syrian border used by Al-Qaida to smuggle foreign fighters into Iraq. Ten U.S. Marines and 139 insurgents were killed in "Operation Steel Curtain," which began Nov. 5 with about 2,500 U.S. troops and 1,000 Iraqi soldiers, a military statement said.
U.S. commanders plan to establish a long-term presence in the area to prevent al-Qaida and its Iraqi allies from re-establishing themselves in the towns of Husaybah, Karabilah and Obeidi along the Euphrates River. They also want Sunni Arabs there to vote in the Dec. 15 national elections without fear of intimidation.
In Baghdad, Iraq's anti-corruption commission said that members of the former government who are under investigation will not be allowed to run in the elections.
A commission official, who asked not to be identified because he is not authorized to speak to the press, said Minister of Public Works Nasreen Berwari, who is the wife of Vice President Ghazi al-Yawer, and Hazem Shaalan, a former defense minister, are among those banned.
