Organizers say climate campaigner Greta Thunberg and other activists set sail Sunday for Gaza on a ship aimed at "breaking Israel's siege" of the territory.

Greta Thunberg and Game of Thrones actor, Liam Cunningham, have teamed up with MEP Rima Hassan on the humanitarian aid ship Madleen which has departed for Gaza.

Greta Thunberg's humanitarian vessel, the Madleen, was intercepted by Israeli commandos while heading to the Gaza Strip, featuring eleven passengers.
