Baghdad, Iraq ? The U.S. military acknowledged Thursday that its two-month drive to crush insurgent and militia violence in the Iraqi capital had fallen short, calling the raging bloodshed disheartening and saying it was rethinking its strategy to rein in gunmen, torturers and bombers.

The admission by military spokesman Maj. Gen. William B. Caldwell came as car bombs, mortar fire and shootings across the country killed at least 66 people and wounded 175. The dead included the Anbar province police commander, slain by gunmen who burst into his home in Ramadi.

The U.S. military also announced the deaths of three U.S. troops in fighting, raising the toll for American troops in October to 74. The month is on course to be the deadliest for U.S. forces in nearly two years.

The high death tolls this month for both Americans and Iraqis have pushed the long and unpopular war back into the public eye in the United States, forcing the Bush administration and the military to address difficult questions in the final weeks of the midterm U.S. election campaign.

Vice President Dick Cheney said the United States was not looking for a way out of Iraq. “I know what the president thinks. I know what I think. And we’re not looking for an exit strategy. We’re looking for victory,” Cheney said in an interview posted on Time magazine’s Web site Thursday.

‘Disheartening’

Caldwell told reporters the U.S.-Iraqi bid to crush violence in the capital had not delivered the desired results, with attacks in Baghdad rising by 22 percent in the first three weeks of the Muslim holy month of Ramadan when compared with the three previous weeks.

“In Baghdad, Operation Together Forward has made a difference in the focus areas but has not met our overall expectations in sustaining a reduction in the level of violence,” Caldwell said at a news briefing. He was referring to the security sweep, which began Aug. 7 with the introduction of an additional 12,000 U.S. and Iraqi troops into Baghdad.

“The violence is indeed disheartening,” he said.

Caldwell said U.S. troops over the last week were forced to launch a second sweep of southern Baghdad’s Dora district after a surge in sectarian attacks. At least eight people, including four policemen, were killed in bombings and shootings in Dora on Thursday, police said.

“We find the insurgent elements, the extremists are in fact punching back hard, they’re trying to get back into those areas,” Caldwell said.

He said security plans were being reviewed for the sprawling, low-rise capital of 6 million people, where rival Shiite and Sunni Muslim sects live in uneasy proximity to each other and the bodies of victims of sectarian death squads are found dumped on the streets each morning.

“It’s clear that the conditions under which we started are probably not the same today and so it does require some modifications of the plan,” Caldwell said.

Political tension

His gloomy assessment came amid tensions between the United States and the nearly 5-month-old government of Prime Minister Nouri al-Maliki.

Frustration over al-Maliki’s failure to crack down on sectarian groups could be exacerbated by revelations that the prime minister ordered U.S. troops to release Mazin al-Sa’edi, a top organizer in western Baghdad for radical Shiite cleric Muqtada al-Sadr.

Caldwell said al-Sa’edi was freed after being detained Wednesday with five aides for suspected involvement in Shiite violence. Al-Sadr’s al-Mahdi Army has been blamed for sporadic attacks and for inspiring groups kidnapping and killing Sunnis.
