(ANSA-AFP) - BUDAPEST, 20 SET - Hungary's foreign minister on Saturday demanded that the European Union copy US President Donald Trump's move to classify the Antifa anti-fascist movement as a "terrorist" group. Following up on his response after the killing of conservative activist Charlie Kirk, Trump on Wednesday announced that he would designate Antifa -- a diverse band of far-left groups with no clear leadership -- as "a major terrorist organisation". Hungary's nationalist Prime Minister Viktor Orban is a key Trump ally in Europe and Foreign Minister Peter Szijjarto said that the government was "convinced that on such a crucial matter Europe must align its steps with the US, the leading force in the global fight against terrorism". In a post on X, Szijjarto released excerpts from a letter he sent to the EU foreign affairs chief Kaja Kallas demanding action against Antifa. "This violent far-left network has carried out brutal attacks across Europe, including in Budapest. To our great regret, suspects later avoided justice by finding refuge in EU states," he said. Szijjarto highlighted the case of Italian Ilaria Salis, who he said "gained immunity after becoming an MEP". Salis was arrested with other activists in Budapest in February 2023 while taking part in a protest against an annual commemoration by neo-Nazis. She was elected to the European parliament one year later, so her house arrest in Budapest was ended. The Antifa movement emerged in the United States mainly after Trump started his first term in 2016. It has no head or national organisation and seemed to be made up of "independent, radical, like-minded groups and individuals," a Congressional Research Service analysis found in 2020. Some critics have said Trump's move could be used as a pretext to quash dissent and target political rivals. (ANSA-AFP).
