Israel has blocked the Global Sumud Flotilla carrying humanitarian aid to Gaza, with reports of its navy boarding some ships, including Alma and Sirius. Italy’s largest labor union has announced a nationwide strike in protest, following demonstrations in cities such as Naples. Organizers say broadcasts from most vessels stopped as Israeli forces surrounded them. While some ships were halted, others continue toward Gaza. The flotilla includes 45 civilian vessels with 500 people, among them lawmakers, activists, and Greta Thunberg.
