Iraq car bomb kills 27 Shiite pilgrims

BAGHDAD: A suicide attacker detonated a car bomb Friday alongside a crowd of Shiite pilgrims walking to a holy city south of Baghdad, killing at least 27 people and wounding 60, Iraqi police officials said.

It was the third deadly bombing this week hitting a major religious ceremony in which hundreds of thousands of Shiites have been converging on the holy city of Karbala. Friday's attack struck during the culmination of the pilgrimage.

This week's violence took place as Iraqi politicians argued over an effort to bar hundreds of candidates from running in the March 7 parliamentary elections because of suspected ties to Saddam Hussein's regime. Prime Minister Nouri al-Maliki said Thursday he would not allow the U.S. ambassador to meddle in the dispute, which Washington fears could frustrate Sunni-Shiite reconciliation.

Friday's blast occurred shortly after noon just east of one of three main entrances to Karbala, a police official said. At least 60 were wounded in the explosion, he added.

Two mortar rounds hit the same area after the car bomb exploded, the official said, adding that the death toll was likely to rise.

The attack came at the height of the pilgrimage when roads around Karbala, 50 miles (80 kilometers) south of Baghdad, were clogged with people trying to reach the city by Friday, another police official said.

The officials spoke on condition of anonymity because they were not authorized to release the information.

The Arbaeen holy day marks the end of 40 days of mourning after the anniversary of the death of Imam Hussein, a revered Shiite figure.

The attack was just a short distance from where a motorcycle bomb exploded two days earlier, killing dozens. On Monday, a female suicide bomber killed at least 54 pilgrims in an attack just north of Baghdad.

Iraqi security forces have increased protection for pilgrims but face huge challenges trying to find a single attacker in the crowds.

Tension also escalated this week between al-Maliki's Shiite-led government and Iraq's Sunni politicians over the push to ban some candidates from next month's election.

A parliamentary committee responsible for rooting out Saddam loyalists blacklisted more than 450 politicians, but an appeals court overturned the ban on Wednesday.

Al-Maliki denounced the ruling, and election officials have asked Iraq's highest judicial authority for a final ruling.

The U.S. is deeply worried the ban could undercut the credibility of the election among Iraqis and cripple efforts to reconcile majority Shiites and the Sunnis who dominated Iraq under Saddam.

U.S. Ambassador Christopher Hill applauded the decision to lift the ban and has said that Iraq must have a credible election.

Al-Maliki warned Hill not to get involved.

"We will not allow American Ambassador Christopher Hill to go beyond his diplomatic mission," al-Maliki said late Thursday in a statement published on his political coalition's Web site.

Al-Maliki said the ban on the candidates should be implemented and that Iraq must not bow to U.S. pressure.

The U.S. Embassy dismissed the warning, saying that Hill has been doing what any diplomat normally does — offering his government's views on issues that could affect American interests.

"That is not going beyond the bounds of acceptable diplomacy. Iraqi leaders take on board our views but then make their own decisions," said an embassy statement issued to The Associated Press. "Of course, we respect Iraqi sovereignty."
