BAGHDAD – Insurgents wearing military uniforms stormed Iraq's central bank Sunday during an apparent robbery attempt, battling security forces in a three-hour standoff after bombs exploded nearby in a coordinated daylight attack that left as many as 26 people
dead.

The assault on Iraq's top financial institution stoked fears that insurgents are taking advantage of political deadlock after inconclusive March 7 national elections to try
to derail security gains as the U.S. prepares to withdraw its forces by the end of next year.

The 325-member parliament was due to convene Monday, but analysts have said agreement on a new government could still be months away.

Iraqi military spokesman Maj. Gen. Qassim al-Moussawi blamed the attack on al-Qaida in Iraq but said no money had been stolen from the bank, which holds gold deposits
as well as U.S. and Iraqi currency.

The violence began with the bombings — which sent plumes of smoke over the city skyline — although there were conflicting reports about the number and nature of the blasts.

The first bomb went off on the road near an electrical generator, al-Moussawi said. Insurgents wearing army uniforms then tried to enter
the bank through two entrances, exchanging gunfire with the guards.

He said three suicide bombers detonated their explosives vests at the main entrance of the bank, while two other militants were killed by security forces at the second gate.

Iraqi security forces then stormed the building, prompting a standoff that lasted at least three hours, according to al-Moussawi's account.

An unknown number of attackers managed to get to a higher floor and set a fire to burn some documents and may have escaped by blending in with
the bank employees, he added, saying the motive appeared to be to steal
the bank's deposits, then blow up the building.

Local police officers said a bomb in a parked car also exploded about 900 yards from the bank.

Al-Moussawi said 15 people were killed, but police and hospital officials later put the casualty toll at 26 dead and more than 60 wounded.

Ghayth Abdullah, the 37-year-old owner of a nearby clothing store, said the blast sent people running from the site, including dozens of women who
worked at the bank. He blamed the government for failing to protect the
people.

"I was not thinking about my property or livelihood," he said. "My worry was what would happen to my family if I were killed by the blast or random shots from the crossfire."

Violent robberies that bear some of the hallmarks of politically motivated attacks have been on the rise in Iraq, as sectarian violence ebbs. Iraqi officials
have attributed at least some of them to cash-strapped militants
desperately trying to raise money for their operations.

But Sunday's attack appeared also to have a political motive as insurgents led by al-Qaida in Iraq seek to undermine confidence in the U.S.-backed government
and other state institutions. It was reminiscent of violence that was
common at the height of sectarian violence that almost pushed the
country to the brink of civil war in 2006-2007 before a series of
U.S.-Iraqi offensives.

Insurgents have targeted government institutions several times over the past year.

Gunmen also killed two policemen in the northern city of Mosul, which has been one of the hardest areas to tame since the 2003 U.S.-led invasion,
according to Iraqi officials.

All the Iraqi officials spoke on condition of anonymity because they weren't authorized to release the information.

The narrow victory of the Sunni-backed Iraqiya party in the March 7 parliamentary vote was initially heralded as a groundbreaking step
toward a secular Iraqi government after years of Sunni-Shiite tensions.

But an alliance between Prime Minister Nouri al-Maliki and another major Shiite coalition, brokered with the help of Iran, has
sparked months of political maneuvering, leaving the government in
limbo.

In a sign resolution was still far away, senior Iraqiya member Hassan al-Allawi said he would not lead Monday's opening parliamentary session as had been planned, saying it would take up to five months to
form a government and he didn't want to hold the job that long. He said
he has handed over the job to Kurdish lawmaker Fouad Massoum.

Earlier Sunday, an independent public watchdog panel said Iraq's government suffered more corruption last year than any other since the U.S.-led invasion in 2003. Rahim al-Ogaili, chairman of
Iraq's Commission on Public Integrity, cited 7,797 cases of waste,
fraud and abuse in 2009 that resulted in the loss of about 842 billion
Iraqi dinars, or about $718 million. He did not give details about how
the money was wasted, or the total funds lost since 2003.

Al-Ogaili, whose panel reports to parliament, said Iraqi leaders largely ignore evidence of corruption, adding: "There are no real and serious measures to fight it."

The trial of British security contractor Danny Fitzsimons also was postponed until Aug. 4. He is accused of
fatally shooting two colleagues, a Briton and an Australian, during a
fight in Baghdad's Green Zone last summer.
