Italian police arrest Milan researcher on terrorism charges; wife also investigated

Italian police arrested 30-year-old researcher Youssef Siher in Milan on terrorism charges for inciting violence and organizing unrest through social media. His wife is also under investigation for the same offenses. Prosecutors allege Siher created the "October 17 Movement" to intimidate the population and pursue subversive goals, with messages reaching up to 150,000 people. He reportedly called for permanent Saturday mobilizations in eight cities until the government falls. Investigators are examining potential links to Hamas financiers and Russian-affiliated hackers, though no direct connections to recent riots have been established. Siher previously praised Hamas's October 7, 2023 attack and referenced an Egyptian revolt manual.
