Sean Paul Kelley at The Agonist raises an interesting question about the "evidence" being presented that implicates Iran in smuggling weapons to Iraqi insurgents...
Wouldn't the numbers be in Farsi? According to my research, the number "81" in Farsi would look more like "^|". (The characters in the lower right corner of each key in the picture below are the Farsi characters).
So... Why would Iranian munitions manufacturers write in English when manufacturing mortars for fellow Farsi speakers?
Later versions of the story are saying that the mortar in the picture might have come from Pakistan. Looking at the picture of a Pakistani mortar, it makes sense.
