For the third time in three days, insurgents on Tuesday bombed an Iraqi bridge, badly damaging a span over the main north-south highway leading from Baghdad, police reported. The attack occurred 60 kilometers south of Baghdad and just 10 kilometers south of a bridge brought down on Sunday by what was believed to be a suicide truck bomber. Three US soldiers guarding that bridge were killed in Sunday's blast. The explosion at 7:30 a.m. Tuesday - not thought to be a suicide bomb - struck a bridge linking the villages of al-Qariya al-Asriyah and al-Rashayed in northern Babil province. No injuries were reported.
