A civilian flotilla carrying humanitarian aid and over 350 activists—including climate icon Greta Thunberg—has departed Barcelona for Gaza, aiming to break Israel’s long-standing naval blockade. Dubbed the Global Sumud Flotilla, this is the largest coordinated maritime mission to Gaza in history.

The flotilla, comprising over 50 vessels from 44 countries, is expected to converge in Tunis before heading east toward Gaza. Organizers say the journey will take 7–8 days, covering over 3,000 km.

“We are sailing again to break the siege and open up a humanitarian corridor,” Thunberg said in a video message.

The mission was briefly delayed due to stormy weather, with winds exceeding 56 kph forcing the boats to return to Barcelona on August 31. They resumed their journey the following evening.

Among those aboard are prominent activists and personalities: Greta Thunberg (Swedish climate activist), Mandla Mandela (grandson of Nelson Mandela, leading the South African delegation), Ada Colau (former Mayor of Barcelona), and Liam Cunningham (actor from Game of Thrones).

“What sort of world have we slid into where children are making their own funeral arrangements?” — Liam Cunningham, referencing a Gaza child’s viral video.

Israel has intercepted similar flotillas in the past, including the infamous Mavi Marmara incident in 2010. This time, Israeli officials have warned they will block the boats again, citing security concerns.

Human rights organizations, including Amnesty International, have accused Israel of committing genocide in Gaza, citing famine and mass displacement.

“Israel has carried out acts prohibited under the Genocide Convention,” said Agnes Callamard, Secretary General of Amnesty International.

“This is not a stunt. It’s a lifeline.” — Saif Abukeshek, Palestinian Activist

The flotilla is expected to reach Gaza waters around September 14–15, coinciding with the UN General Assembly in New York—a strategic move to maximize global attention.

Israel’s response remains uncertain, but activists vow to continue their mission, even if intercepted.
