France accuses Iran of freezing its refrigerators.
For a week, unidentified hackers have been attacking supermarket chains and warehouses, causing refrigeration equipment to raise temperatures. The cost of the spoiled food is estimated at hundreds of millions of euros.
France's foreign minister blamed the Islamic Revolutionary Guard Corps for the attacks.
"The Revolutionary Guards are responsible for this cyber attack - and there will be consequences," said Jean-Noël Barrow.
