Yes, squirrels. According to the Islamic Republic News Agency:
The squirrels were carrying spy gear of foreign agencies, and were stopped before they could act, thanks to the alertness of our intelligence services.So far as I can see, this is no joke.
In fact, it rather reminds me of the recent claims that British troops had released man-eating badgers (!) into the environs of Basra, in an effort to spread panic among the people living there. Which gives rise to the intriguing question, has the animal kingdom thrown its weight behind Western civilisation, in the war with Islam?
Because the only other explanation is that many Muslims are utterly insane, and that couldn't possibly be true, could it?
