Last night, the Global Sumud (“Steadfastness”) Flotilla — the fleet of dozens of boats manned by participants from more than forty countries that aims to defy the Israeli siege of Gaza and get humanitarian aid to the starving Palestinians — came under attack.

It was the second time the flotilla has been attacked since starting its journey in late August, after two drones dropped projectile explosives on the boats while they were docked in Tunis a fortnight ago. This time, a swarm of drones attacked the flotilla, jamming their communications (with ABBA songs, seemingly a mocking nod to Swedish activist Greta Thunberg, one of the flotilla’s participants), and leaving one of the boats destroyed.

There is little doubt about who is behind the attacks. Donald Trump’s special envoy to Syria, Tom Barrack, had earlier this week casually admitted that Israel was responsible for the drones in Tunis, telling an interviewer that “Israel is attacking everybody,” listing Tunisia alongside Syria and Lebanon. This latest attack comes after days of the Israeli government accusing the fleet of being a “jihadist” and “Hamas flotilla” that had been “organized” by the terrorist organization, and threatening to “take the necessary measures to prevent its entry into the combat zone.” It was an ominous sign that Israel was gearing up for another attack.
