Afghan officials said US-ordered bombing runs killed dozens of civilians taking shelter Tuesday from a battle with Taliban militants, and villagers took several truckloads of bodies to show the provincial governor. The US promised a joint investigation. A provincial councilman said he saw about 30 bodies, many of them women and children. Overall death toll estimates varied widely. Villagers estimated from 70 to well over 100 civilians may have died, according to local and regional officials. But no government official could confirm such a toll.
