More Than 50 Killed in Iraq

Iraqi Prime Minister Nouri al-Maliki has promised a "decisive battle" against the terror network in Mosul but given no start date. The U.S. military has warned it will not be a swift strike, but rather a grinding campaign that will require more firepower.

An al-Qaida front group for northern Iraq warned last week in an Internet statement that it was launching its own campaign in Mosul and surrounding areas.

In all, 70 people were reported killed or found dead by police on Sunday, one of the highest nationwide death tolls in recent months. That figure included three policemen who perished in a suicide car bombing at a checkpoint in the Anbar city of Fallujah and 10 bullet-riddled bodies showing signs of torture.

Rear Adm. Gregory Smith, a U.S. military spokesman, said the documents released Sunday offered proof that al-Qaida in Iraq had been severely disrupted by the so-called awakening movement and changing U.S. tactics, but he stressed the terror network was by no means defeated.

The military said the two documents were discovered last year by American troops in November as the Sunni movement that began in Anbar province was spreading to Baghdad and surrounding areas.

One was a 39-page memo written by a mid- to high-level al-Qaida official with knowledge of the group's operations in Iraq's western Anbar province; the other a 16-page diary written by another group leader north of Baghdad.

The documents tell "narrow but compelling stories of the challenges al-Qaida in Iraq is facing," Smith told reporters in Baghdad. "This does not signal the end of al-Qaida in Iraq, but it is a contemporary account of the challenges posed to terrorists from the people of Iraq."

He said the documents are believed to be authentic because they contain details that only al-Qaida in Iraq leaders could know about battlefield movements and tactics. The U.S. military gave reporters partially redacted copies of the full diary but only four pages of the Anbar document, citing security reasons. Both were provided in the original Arabic and an English translation.

In the Anbar document, the author acknowledges a growing weariness among Sunni citizens of militants' presence and the U.S.-led crackdowns against them. He also expresses frustration with foreign fighters too eager to participate in suicide missions rather than continuing to fight.

"The Islamic State of Iraq is faced with an extraordinary crisis, especially in al-Anbar," the author wrote, referring to an umbrella group of insurgents led by al-Qaida.

Smith also quoted the document as lamenting the loss of "cities and afterward, villages," adding "we find ourselves in a wasteland desert."

It said U.S.-led forces had learned from their mistakes and improved security had made it harder to transport weapons and suicide belts and forced foreign fighters to go underground because of their distinctive dialects.

The military said the memo was believed to have been written last summer and was intended for the author's superiors.

The diary, seized by U.S. troops south of Balad, was written in autumn 2007 by Abu Tariq, who refers to himself as sector leader for al-Qaida in Iraq. Tariq wrote that he was once in charge of 600 fighters, but only 20 were left "after the tribes changed course" _ a reference to how many Sunni tribesmen have switched sides to fight alongside the Americans, Smith said.

The Sunni tribes' alliance with U.S. forces is credited with helping reduce violence across the country, along with an influx of some 30,000 American troops. A security crackdown that began in Baghdad and surrounding areas a year ago also has driven the militants north.

Mosul, 225 miles northwest of Baghdad and the capital of Ninevah province, is believed to be the last major urban stronghold for al-Qaida in Iraq.

"The diary shows that al-Qaida regards these volunteer citizen groups as a grave threat, and that terrorists are targeting them," Smith said.

In recent months, attacks on the Sunni volunteers have spiked while overall violence has steadily declined, he noted, adding that at least 77,500 volunteers have partnered with U.S. and Iraqi troops countrywide.
