Details are still scarce, but officials are confirming that US troops attacked a civilian bus in the Herat Province, in the Adraskan District. The attack killed one civilian and wounded another.

So far there have been no comments from US officials as to why the bus was attacked, but it was traveling on the same Kabul-Herat highway as the US convoy was, and it is not unusual for US troops to perceive anything else on the road as a “threat” and start attacking it.

This is the second report incident of civilians killed this year in Herat. In February, four civilians were killed in the cross-fire between a NATO and Taliban gunbattle in the province.

It is also the second incident of US troops killing civilians this week, with 11 children killed in a US air strike in Kunar Province, on the other side of the country, earlier this week.
