Activists aboard the Global Sumud Flotilla, including Greta Thunberg and Mandla Mandela, reported that the Israeli navy began intercepting their vessels as they approached Gaza. The flotilla, consisting of nearly 50 boats and 500 activists, is carrying humanitarian aid. Israeli officials warned the flotilla to change course, labeling it a provocation, while European governments urged the activists to avoid confrontation. The legality of Israel's blockade and the right to provide humanitarian aid are debated among experts.
