Agreed. There is nothing to be gained from acting like we know better than Iran's own officials. It's just self-gratification for your own ego, trying to feel smug and superior, but you are only helping the enemy when you act this way. It's a very simple rule during wartime: don't help the enemy's propaganda!

And also, it is very likely that this was a translation issue. There are already credible reports that the US suffered hundreds of casualties which does not just mean killed, it means killed and injured which is most likely what the minister was referring to.
