France vows tough response to freezer cyberattack blamed on Iran

France's foreign minister said Tuesday that Paris ruled out "nothing" to respond to a major cyberattack on hundreds of supermarket fridges in October that it has blamed on Iran.

Foreign Minister Jean-Noel Barrot told FranceinfoTV that Iran's ambassador would be summoned and European-level sanctions would be sought.

"I can also tell you that we rule nothing out and will take all measures -- including those we may not disclose publicly -- that we deem proportionate and necessary to deter any further attacks," he added.

The goal, Barrot said, is "to deter anyone who might be tempted, in Iran or elsewhere, to do it again".
