It is totally unsurprising that the Iranian government blames the Mossad for what is clearly an act of Islamic terror. However, I was a bit taken aback to see the Iranian state media promoting this insane story on their english language website. Just take a gander at the beginning of their report:

The explosion at a church in the Egyptian city of Alexandria, which left 21 people killed and another 80 Muslims and Christians wounded, raises one question: Who was behind the blast?Although, at first glance, the finger is pointed at extremist Wahabi or Salafi groups, it goes without saying that no Muslim, whatever their political leanings may be, will ever commit such an inhumane act.Attacks on churches in Egypt, Lebanon, Iraq and Tunisia can be analyzed in the context of a Zionist scenario aimed at driving a wedge between Muslims and Arab Christians.Since the emergence of Islam, Muslims and Christians in the East have always coexisted peacefully as Islam pays due respect to the freedom of divine faiths -- especially Christianity.In Egypt, too, Muslims and Christians are living in peace and harmony. Never, ever have the Christians in Egypt complained of any problems keeping them from carrying out their religious duties.

Uhh... sure. Now how on earth do you even begin to negotiate with a regime that happily pumps out such brazen lies with such regularity? Beats me.
