How could you prove it was not a US bomb?
All they have to do is trot over the one of the military targets, grab a piece of a tomahawk, and bring it to the market place.
Were we bombing in that area? I suppose if we could put a tomahawk in Iran, and one in Turkey, we could have accidentally put one in the market.
This sort of thing is going to happen. It's unforunate, and a very disheartening event, but we all knew there would be some civilian casualties in this war.
Sad....very sad.
