The Pentagon has acknowledged for the first time Afghan civilians were killed by US bombs earlier this week. The toll from Monday’s bombing in Farah province remains unknown, with estimates topping 100 civilians, including many women and children. On Thursday, a Pentagon official admitted to the New York Times initial US claims of Taliban grenades causing the deaths were “thinly sourced.” Local residents have said the damage was far too extensive for any Taliban weapon to cause. On Thursday, hundreds of Farah residents protested outside the provincial governor’s office demanding the withdrawal of all foreign troops. Three demonstrators were wounded after Afghan police officers opened fire.
