(Baghdad, Iraq-AP) -- Another ambush in Iraq -- and another death of a U-S soldier. The U-S military reports one soldier was killed and another injured today in an attack in the so-called "Sunni Triangle," where support for Saddam Hussein has been the strongest. U-S Central Command says the attack happened on a road north of Baghdad. As in numerous earlier ambushes, insurgents reportedly shot rocket-propelled grenades and small-arms fire at the troops. The latest death means 153 American troops have been killed in action in Iraq since the start of the U-S-led war.
