France summoned the Iranian envoy after accusing Tehran of supermarket break-ins.
France summoned Iran's ambassador on Tuesday over allegations that Tehran was behind a cyber attack that disrupted the refrigeration systems of hundreds of supermarkets across Europe in October. French Foreign Minister Jean-Noel Barrow said Paris would push for EU sanctions and warned that France could respond by cyber means, including undisclosed actions, to deter further attacks and hold those responsible accountable. The UN mission in Tehran did not respond to requests for comment and Iran routinely denies involvement in malicious cyber operations.
