Car bombs kill 12 Iraqis

BAGHDAD, Iraq -- Car bombs killed at least a dozen people in Baghdad and another major city Tuesday as pressure mounted on interim Prime Minister Ayad Allawi to avert a full-scale U.S. attack on the insurgent stronghold Fallujah.

There was no word on an American and two other foreigners abducted Monday night in Baghdad, although the kidnappers freed two Iraqi guards also captured in the bold attack. Some diplomats speculated the foreigners may have been seized to pressure the Americans against a Fallujah attack.

In northern Iraq on Tuesday, saboteurs blew up an oil pipeline and attacked an oil well.

At least eight people, including a woman, died early Tuesday when an explosives-laden car slammed into concrete blast walls and protective barriers surrounding the Education Ministry and exploded in Baghdad's Sunni Muslim district of Azamiyah.

In Mosul, 225 miles northwest of Baghdad, a car bomb exploded near a military convoy carrying an Iraqi general, killing four civilians and wounding at least seven soldiers.

The violence came as American forces prepare for a major offensive against Fallujah and other Sunni militant strongholds north and west of Baghdad in hopes of curbing the insurgency so that national elections can be held in January.

U.S. forces have pounded insurgent positions around Fallujah almost daily, but American officials say the go-ahead for an all-out assault must come from Allawi, the interim prime minister.

However, new pressure mounted Tuesday on Allawi, a Shiite Muslim, to forego an assault and to continue negotiating with the hardline Sunni clerics who run the city, which has become a symbol of Iraqi resistance throughout the Arab world.

Mohammed Bashar al-Faidhi, spokesman of the Association of Muslim Scholars, said his clerical group would use "mosques, the media and professional associations" to proclaim a civil disobedience campaign and a boycott of the January elections.

"In the case of an incursion in Fallujah, there will be a call to boycott elections," al-Faidhi said. "In case of an incursion, more deterrent steps will be taken."

He said that a boycott call by the influential clerical group "will have a great resonance among the people of Iraq."

Such a call by Iraqi Sunnis would probably draw little support among the Shiite majority, believed to comprise about 60 percent of Iraq's nearly 26 million people. The country's leading Shiite cleric, Grand Ayatollah Ali al-Sistani, has been demanding elections for more than a year, and some Shiite preachers have been telling their followers that failing to vote would be sinful.

However, a boycott call could have resonance among central Iraq's Sunnis, who form the core of the insurgency, and inflame passions between the country's major religious communities. Interim President Ghazi al-Yawer, a Sunni, has also spoken out against an attack.

"It's not reasonable to call for elections that are supposed to be democratic and yet a peaceful city gets attacked by weapons, missiles, planes and bombs," said Nabil Mohammed, a professor at Baghdad University's Center for International Studies. He said an all-out attack would "elicit a very big response and support from Iraqis."

U.S. officials believe Fallujah is the stronghold of an al-Qaida faction led by Jordanian militant Abu Musab al-Zarqawi, whose followers are responsible for numerous car bombings and beheadings of foreign captives.

Al-Zarqawi's group claimed in a Web posting Tuesday that it beheaded Japanese backpacker Shosei Koda after Tokyo refused to withdraw troops from Iraq. The claim was accompanied by a gruesome video showing the young Japanese, whose body was found Saturday in Baghdad, being beheaded on an American flag.

No group has claimed responsibility for the attack in Baghdad in which an American, a Filipino and a Nepalese were taken hostage.

Two Iraqi guards were released after kidnappers beat them and warned them against working for foreigners, police said. The captives are believed to work for a Saudi company that caters food for the Iraqi army.

Twelve Americans have been kidnapped or are missing in Iraq. At least three of them have been killed -- all beheaded by al-Zarqawi's group.
