The Freedom Flotilla Coalition defines itself as "an international civilian mission responding to international failure" and has focused its efforts on Gaza.

Israeli forces intercepted and boarded a sailboat carrying a group of activists, including climate campaigner Greta Thunberg, who planned to bring humanitarian aid to Gaza in defiance of an Israeli blockade on the enclave.

Israel said the passengers would return to their home countries and the aid would be delivered to Gaza through established channels.
