Greta Thunberg has criticized governments for failing to uphold international law, stating that aid flotillas to Gaza would not be necessary if officials fulfilled their legal duties. Thunberg is set to join the Global Sumud Flotilla, which aims to deliver humanitarian aid and open a corridor to Gaza, challenging what organizers call Israel's illegal siege. Previous attempts to deliver aid by sea in June and July were blocked by Israeli forces, with activists detained and expelled. The current mission, described as the largest solidarity effort yet, comes amid worsening conditions in Gaza and international debate over responsibility for the humanitarian crisis.
