Israel announced its intention to “act accordingly” to prevent the Freedom Flotilla Coalition, which includes climate activist Greta Thunberg, from reaching the Gaza Strip.

Thunberg, 22, a Swedish eco-warrior, set sail this week aboard the Madleen hoisting a Palestinian flag with 11 other activists. It will try to reach the shores of the Gaza Strip to bring in some aid and raise awareness over the humanitarian crisis there. 

“We are doing this because, no matter what odds we are against, we have to keep trying,” Thunberg said.

Last month, an earlier Freedom Flotilla Coalition ship was damaged just before arriving at the Mediterranean island of Malta to pick up Thunberg for a similar mission, the New York Post reported. The group accused Israel of attacking the vessel with drones.

During her voyage, which began in the Sicilian port of Catania in southern Italy, Thunberg has been filming content for social media, including swimming in the sea.

“Because the moment we stop trying is when we lose our humanity. And no matter how dangerous this mission is, it’s not even near as dangerous as the silence of the entire world in the face of the livestreamed genocide,” she said before setting sail.
