BAGHDAD (AP) -- This much is agreed - a double bombing in Baghdad struck a school bus and those responding to the first blast. But the difference in casualty figures was stark. Iraqi officials said 31 people died; the U.S. military put the death toll at five.
The conflicting reports from Monday's attack are emblematic of a spate of recent bombings that have raised fears of a resurgence in violence.
There have always been disagreements because accurately counting the dead in the chaos of Iraq's war has never been easy. Yet discrepancies appear to be widening as the political stakes grow.
U.S. officials privately say that some officials in the Shiite-dominated Interior and Health ministries could possibly have political or personal motives for inflating casualty numbers for bombings in mainly Shiite areas.
Iraqi officials insist their tallies are more accurate, saying the figures are based on death certificates issued by hospitals and the number of wounded who receive treatment.
The increase in attacks comes at a sensitive time for Iraq, with political tensions heating up ahead of provincial elections that are due to be held by Jan. 31 and are expected to shift some power to the disaffected Sunni minority.
Sunni and Shiite extremists also oppose negotiations that are under way over a proposed U.S.-Iraqi security pact that would extend the presence of American forces in the country beyond the end of the year.
U.S. officers acknowledge the difficulties in establishing accurate numbers but express confidence their figures come close thanks to an increased presence of American troops who have spread throughout the community to work with their Iraqi counterparts.
American soldiers race to the site of bombings, often with the Iraqi security forces that are responding to the attacks. Those troops interview witnesses as well as rescue crews to reach a consensus on casualties and the type of attack, the military said.
"We do have enough soldiers throughout the battle space that when there is an explosion, we hear it and basically we run to the sound of the gun," said Lt. Col. Steve Stover, a spokesman for U.S. forces in Baghdad.
If the U.S. military is unable to promptly reach the scene, it depends on casualty reports from American transition teams working with the Iraqi security forces that do.
It's a change from earlier in the war, when American troops focused on fighting insurgents and often declined to provide civilian casualty information.
Adel Muhsin, a top Health Ministry official, said the Americans generally aren't getting the full picture, pointing out that victims often die of their wounds at the hospital or on the way there.
"The U.S. figures are based on the preliminary reports. Usually, the first view is not completely dependable because the site is still chaotic," Muhsin said. "Preliminary and initial figures taken shortly after the explosion tend to be small."
"I could easily imagine that the U.S. government would want to get a low number, which would suggest that peace is at hand, and that al-Sadr might want a high number to suggest that maybe al-Maliki is not doing such a good job after all," Pike said. "You could imagine both methodological and political explanations for the discrepancy."
The issue came to the fore this week when a series of bombings targeting Shiite areas over three consecutive days rattled the growing sense of confidence among Iraqis about security gains.
- On Monday, the Interior Ministry said 27 people were killed in the bus attack. Police and hospital officials contacted by Associated Press staff put the death toll at 31, which would make it the deadliest blast in the capital in six weeks. The U.S. military, citing Iraqi army figures, said five were killed.
- On Tuesday, Iraqi police and hospital officials said three people died when twin blasts hit a newspaper delivery truck and nearby vendors. The U.S. military said 18 people were wounded, including three Iraqi policemen and 15 civilians.
- On Wednesday, Iraqi police and hospital officials said 23 people were killed in a series of bombings in mostly Shiite areas of the capital. The U.S. military said one civilian died and 46 were wounded in four separate attacks.
Iraq Body Count, an independent organization that tracks media reports as well as official figures, put the death tolls at 27 in Monday's attack, four on Tuesday and 28 on Wednesday.
Violence is down significantly in Baghdad since the worst of the Sunni-Shiite fighting in 2006 and 2007 and the U.S. troop buildup of last year. But attacks in Baghdad continue daily, albeit at a lower level than in previous years.
An AP tally showed at least 26 deadly bombings in the Baghdad this month, as of Wednesday, compared with 28 for all of October and 22 in September. At least 102 people were killed this month in the capital, compared with 95 for October and 96 in September, according to the AP count.
"There's been a slight uptick," said Stover, the military spokesman. "I think they're going into a political period in this country. With the power struggle ... there will be an increase in attacks."
