Again, from the latest update on abcnews.go.com: "There was also a pre-planned U.S. attack in the area that night, with B-52 bombers dropping seven 2,000-pound bombs on a cave and tunnel complex as well as on a nearby anti-aircraft position, which had fired on coalition planes in the past. One of those bombs went astray but ground spotters reported it fell on an uninhabited hillside. 'The pre-planned target was out of the village, on a ridgeline in another location,' Colonel Roger King said."

So there were no bombs dropped on the village at all.

All that remains to be determined is whether the bullets that killed and injured the Afghan civilians came from the US airship or not. If anyone did set off a bomb in the village that night, it wasn't dropped there by the US.
