Iran has been blamed for cyber attacks on fridges that raised their temperatures and spoilt millions of pounds' worth of supermarket food.

Jean-Noël Barrot, the French foreign minister, said Iran's revolutionary guards were behind the attacks, adding that there would be consequences for the country.

The Paris prosecutor's office said it had requested international arrest warrants against the leader of Shahid Kaveh, an offensive cyber unit affiliated with the revolutionary guards, and his two deputies.
