BAGHDAD, Iraq (AP) – A suicide bomber struck a crowd of mostly poor Shiites in Baghdad on Tuesday, killing at least 63 people and wounding more than 200 after luring construction workers onto a pickup truck by offering them jobs as they were eating breakfast.

The blast, condemned by both Shiite and Sunni lawmakers, came on a day that saw the U.S. military report the deaths of five more troops. At least 59 other Iraqis were also killed or found dead, including an AP Television News cameraman shot while covering clashes in the northern city of Mosul.

The Baghdad suicide attack shattered storefront windows, dug craters in the road and set fire to several cars. People rushed to the devastated area to see if friends or relatives were killed or wounded. Mangled bodies were piled up at the side of the road and partially covered with paper. Two men sat on the sidewalk, crying and covering their faces with their hands.

The bombing took place about 7 a.m. in Tayaran Square, where men gather daily to solicit jobs as construction workers, cleaners and painters. They buy breakfast at stands selling tea and egg sandwiches while waiting for potential employers to drive up, making them easy targets.

The practice has become increasingly common amid high unemployment and soaring prices, forcing men to hire themselves out daily to feed their families. The Iraq Study Group report released this month by a bipartisan commission in Washington said that unemployment ranges from 20 percent to 60 percent of Iraq’s population.

It was the second major attack in less than a month in which unemployed Shiites were lured to their deaths by a suicide bomber promising to hire them for the day. On Nov. 19, 22 people were killed and 44 were wounded when a minivan driven by a man promising work exploded in the mainly Shiite southern city of Hillah.

Interior Ministry spokesman Brig. Abdul-Karim Khalaf, who gave the official police account of Tuesday’s attack, said at least 63 people were killed and 236 were wounded. Other police put the death toll as high as 71.

Police initially said it was a coordinated bomb attack involving a minivan and a car, but later said there was only one bombing.

Khalil Ibrahim, 41, who owns a shop in the area and suffered shrapnel wounds to his head and back, also thought there were two blasts, saying he fainted after being thrown against the wall by the force of the second.

“I saw people falling over, some of them blown apart,” he said.

Tayaran Square is near several government ministries and a bridge that crosses the Tigris River to the heavily fortified Green Zone, where Iraq’s parliament and the U.S. and British embassies are located.

Most of the victims were Shiites from poor areas of the capital such as Sadr City, said police Lt. Bilal Ali.

Parliament speaker Mahmoud al-Mashhadani, a Sunni, said the attack targeted poor people who were trying to feed their families, “turning them into pieces of flesh” and urged the deeply divided legislature of Shiites, Sunnis and Kurds “to find a solution” to Iraq’s many problems.

Prime Minister Nouri al-Maliki, a Shiite, blamed the “horrible crime” on Sunni extremists. “Iraq’s security forces will chase the criminals and bring them to justice,” he said.

The prime minister has come under fire from powerful politicians who accuse him of not doing enough to stop the sectarian violence that has spiraled since a Feb. 22 bombing destroyed the golden dome of a revered Shiite mosque in Samarra.

On Monday, police discovered a bomb hidden outside the Samarra mosque. The bomb exploded while coalition bomb disposal officials were removing it, slightly damaging the building, the U.S. command said.

Al-Maliki said Tuesday there was no alternative to his national unity government, arguing that talks between major partners in his ruling coalition to form a new bloc in parliament did not amount to a bid to unseat him.

Two key political figures, Vice President Tariq al-Hashemi, a Sunni who was meeting with President Bush on Tuesday in Washington, and senior Shiite leader Abdul-Aziz al-Hakim, have been linked to behind-the-scenes efforts to form a new bloc in parliament that would replace the alliance now supporting al-Maliki’s government.

“What is going on now is positive when the aim, contrary to what has been said, is to broaden the government’s political base and not an attempt to undermine its ideology or to search for alternatives,” al-Maliki told reporters in his first public comments on these efforts.

“There is no alternative in Iraq for this national unity government because it is the guarantee for the political process to continue,” he said.

The White House has denied that any plans were afoot to dump al-Maliki, whose seven months in office have been defined by failure to curb growing violence and improve the lives of Iraqis.

The U.S. command announced the five more deaths of U.S. troops in Iraq, including three Marines killed in combat in Anbar province.

The three Marines assigned to 3rd Marine Aircraft Wing died Monday of wounds sustained while fighting insurgents, according to a statement.

The U.S. military said those killed were not linked to a hard landing Monday by a Marine helicopter in Anbar. At least 18 people were injured in that incident but hostile fire did not appear to be the cause, the military said.

Another Marine died Monday from non-hostile causes in Anbar, which stretches west from Baghdad to the borders of Syria, Jordan and Saudi Arabia.

The military also said a soldier died Monday of apparent natural causes near Diwaniyah, 80 miles south of Baghdad. The soldier lost consciousness and died after being transported to a troop medical clinic.

The American deaths raised to 51 the number of U.S. troops who have died this month. At least 2,939 members of the U.S. military have died since the war began in 2003, according to an AP count.

The slain AP cameraman was Aswan Ahmed Lutfallah, 35, the third Associated Press employee killed in the Iraq war. Before his death, the Committee to Protect Journalists said 89 journalists and 37 media support workers had been killed in Iraq.
