Meanwhile, the top U.S. commander in charge of troops in northern Iraq says that a coalition troop presence will be needed in his region over the next year and a half. But Maj. Gen. Benjamin Mixon told CNN on Wednesday that it is possible the number of troops in the north could drop by sometime next year.
"As I look at my area, I certainly can see we will need some level of troop presence by well into 2009. The numbers will depend on the situation," said Mixon, who has 23,000 troops under his command.
Mixon reported strides in Operation Arrowhead Ripper, the major offensive in and around Baquba that began last month: "We have taken Baquba back from the enemy. We have pushed them into the Diyala River valley and are continuing to attack them in the Diyala River valley."
A U.S. soldier with the 13th Sustainment Command (Expeditionary) died Tuesday of a "non-battle related" cause, the U.S. military said Wednesday. The death put the total U.S. military personnel killed in the Iraq war at 3,637, including seven civilian contractors of the Defense Department. The number of American troop deaths for July is 58.
Also Wednesday, morning raids in three cities by coalition forces targeting al Qaeda in Iraq detained 20 suspected terrorists, according to a U.S. military statement.
"With every operation coalition forces conduct we are further degrading and destroying the al Qaeda in Iraq network," said Maj. Marc Young. "Al Qaeda and its foreign leadership seek only to bring violence and fear to the Iraqi people in its attempt to prevent a secure and democratic Iraq."
The raids took place in Baghdad, Mosul and Tarmiya, according to the statement.
At least 18 slain bodies were found across the capital on Wednesday, the Iraqi Interior Ministry said. The total number of such deaths this month stands at 504. Iraqi authorities suspect the fatalities are the result of sectarian violence. E-mail to a friend
