BAGHDAD - Suspected Sunni insurgents bombed and badly damaged a span over the main north-south highway leading from Baghdad on Tuesday — the third bridge attack in as many days in an apparent campaign against key transportation arteries.
The attack occurred 35 miles south of Baghdad and just six miles south of a bridge brought down on Sunday by what was believed to be a suicide truck bomber. Three U.S. soldiers guarding that bridge were killed in Sunday's blast.
