At least two American soldiers were killed and one was wounded in an ambush in the resistance zone north of Baghdad, the U.S. military reported Sunday. The attack with rocket-propelled grenades and small arms fire occurred at 10:45 p.m. Saturday outside the northern city of Kirkuk, 160 miles north of Baghdad, said Maj. Josslyn Aberle, spokeswoman for the 4th Infantry Division. The U.S. command in Baghdad earlier reported the attack occurred Saturday night southwest of Saddam Hussein's hometown of Tikrit, the 4th Division's headquarters city 100 miles northwest of Baghdad. The conflicting reports on location could not be immediately reconciled. Aberle said a mounted patrol of Task Force Ironhorse - a force that includes her infantry division - was the target of the ambush and returned fire. There was no further fighting, she said. West of Baghdad, another attack left an American armored vehicle ablaze on a road outside the flashpoint town of Fallujah on Sunday morning, witnesses reported. The U.S. command said it had no immediate word on casualties in that incident, 35 miles west of the capital. Resistance forces have mounted an average of 22 attacks a day on the U.S. occupation forces in Iraq in recent weeks, mostly in the so-called "Sunni Triangle," a Sunni Muslim-dominated area stretching from the west of Baghdad to the north. The area was a strong base of support for Saddam's Baath Party regime, which was toppled by the U.S.-British invasion earlier this year. **PHOTO CAPTION*** The rifles, helmets and ID tags of two US soldiers stand in a memorial as Captain Craig Childs bows his head during a remembrance service in the northeastern Iraqi town of Tikrit.
