• US officials seek ‘final end’ to Russia-Ukraine war as talks begin

The EU has said it stands ready “to come with a swift and united response” after France blamed Iran for a spate of cyber-attacks on supermarket freezers and chillers that caused millions of euros of damage.

Speaking to journalists on Monday, French foreign minister Jean-Noël Barrot said “Europe-wide sanctions” would be imposed against those responsible as he announced France believed that Iran’s Revolutionary Guards were “responsible for this attack”.

We acknowledge that France has attributed these (cyber-attacks) to Iran. Pending discussions with member states, we as (the) European Union, we stand ready to come with a swift and united response.

We as the EU, we have consistently called on all states to refrain from malicious behaviour in the cyberspace. And we will continue to address such malicious behavior, making use of all the tools that we have also under the EU cyber diplomacy toolbox, including sanctions.
