Swiss foreign minister Ignazio Cassis has said he signed a joint declaration with his Italian counterpart Antonio Tajani expressing “deep concern” over Russian aggression in Ukraine, but said Moscow should be present at the next peace summit.

Switzerland in mid-June hosted dozens of world leaders at a summit aimed at crafting a pathway towards peace in Ukraine, although Russia was not invited.

Now, Mr Cassis has said on X: “We support holding a second peace summit that includes all parties, including Russia.”
