It’s not unheard of to use animals in warfare, so when Iran found 14 squirrels near their border with espionage equipment, they did the sensible thing and arrested them. The incident was reported by the country’s official news agency, and confirmed by the country’s chief of police, though he said he didn’t have any details. Everyone took the opportunity to make a “this is nuts!” joke, including the UK’s Foreign Office.
Some Iranians were perfectly willing to believe that a foreign power may be turning to bushy-tailed agents. One went so far as to suggest it was the Brits behind it. In any case, there are no further reports of squirrel infiltration, which has left time for Iran to start arresting pigeons instead.
