South African author Zukiswa Wanner has published a new book detailing her experiences while on the Global Sumud Flotilla mission aimed at delivering humanitarian aid to Palestinians in Gaza. The mission, which took place in September 2025, included notable figures such as Mandla Mandela, the grandson of Nelson Mandela, and brought together more than 400 activists from various backgrounds. Wanner's detention by Israeli forces occurred when the activists were intercepted in international waters, a situation that has sparked significant international debate regarding the legality and implications of such actions.

In her book 'Flotilla: A Journey of Conscience', Wanner shares harrowing accounts not only of the interception but also of the treatment she and other activists received while detained. Allegations of torture and mistreatment by Israeli authorities have been reported by several detainees, raising serious concerns about human rights and international law violations. This incident has drawn attention from global activists, including environmentalist Greta Thunberg, who was also part of the flotilla, prompting discussions about the broader implications of humanitarian missions in politically sensitive regions.

Wanner's narrative contributes to the growing body of literature on the Israel-Palestine conflict, offering personal insights into the risks faced by those advocating for peace and humanitarian support. Her experience sheds light on the complexities of international aid efforts and highlights the challenges faced by those seeking to exert influence through non-violent means. The publication of her book and the involvement of high-profile activists may further fuel interest and discourse around the situation in Gaza and the role of international interference in the region.
