BBC:

Three US soldiers were killed and six injured after a suicide bombing caused a bridge across a highway near the Iraqi capital, Baghdad, to collapse.

The soldiers were manning a checkpoint on top of the bridge when a car bomb exploded beneath, the US military said.

The attack on Sunday was the latest in a series by Iraqi militants on bridges.[..]

Sunday's attack on the bridge over the main highway linking Baghdad to southern Iraq brought to at least 28 the number of US troops killed in Iraq so far this month.

UPDATE:  Larry Johnson at NoQuarter and Gorilla's Guides give their analysis on how these bridge bombings leave the military even more vulnerable.
