Iranian weapons?

The media really pisses me off sometimes. I realize that most of the public doesn't understand the subtlety of the middle east, but after four years the media should have a clue. My latest outrage is based on all the reports of Iran providing arms to insurgents. While this may be happening, there's a major problem with the evidence. Here's a picture of the "Iranian" weapons shown to the press by Major-General William Caldwell on 4/11:

BAGHDAD, IRAQ - APRIL 11: Weapons seized in Iraq are
shown during a news conference April 11, 2007 in Baghdad, Iraq.

All the reporters dutifully filed the stories without question. But take a close look at the weapons...anyone have any questions?

Um, let's see...Iranians speak Farsi. I don't expect our media would be able to tell the difference between Farsi and Arabic (although they are very different languages), but the difference between Farsi and English should be obvious. Unless we have been selling arms to the Iranians.

This "evidence" is blatantly obvious propaganda. Will someone, anyone in the media call them on this?

Added: Should have put up source link:

Added again: The military explains:

Several mortar rounds on display at the news conference had markings that read
"2006," suggesting they had been manufactured -- and arrived in Iraq -- after
the U.S.-led invasion in 2003. The markings on all the munitions were in English. Maj. Marty Weber, an explosives expert, said countries selling arms on the global market tend to use English lettering.http://www.washingtonpost.com/wp-dyn/content/article/2007/04/11/AR2007041102121_pf.html

I'm skeptical, to say the least.
