On Tuesday, Israel expelled activist Greta Thunberg, the nation’s Foreign Ministry announced. This came a day after the Israeli military intercepted a ship heading to Gaza with Thunberg onboard.

The Foreign Ministry reported on X that Thunberg took a flight to France before continuing to her native Sweden. They shared an image of Thunberg, known for advocating against air travel for climate reasons, sitting on the airplane.

Thunberg was among 12 individuals aboard the Madleen, a vessel delivering aid to Gaza. The trip aimed to protest Israel’s ongoing conflict in the region and draw attention to the humanitarian issues faced by the Palestinian population, as noted by the Freedom Flotilla Coalition, the organization behind the mission.

Israeli naval forces seized the boat without incident early Monday about 200 kilometers (125 miles) off of Gaza’s coast, according to the coalition, which along with rights groups, said Israel’s actions were a violation of international law. Israel rejects that charge because it says such ships intend to breach what it argues is a lawful naval blockade of Gaza.

The boat, accompanied by Israel’s navy, arrived in the Israeli port of Ashdod Monday evening, according to the Foreign Ministry.

Other activists face deportation

Adalah, a legal rights group in Israel representing the activists, said Thunberg, two other activists and a journalist had agreed to be deported and leave Israel. The other eight activists refused deportation, were being held in detention and their case was set to be heard by Israeli authorities, Adalah said. The activists were expected to be brought before a court later Tuesday, the group added.

Sabine Haddad, a spokeswoman for Israel’s Interior Ministry, said the activists who were being deported Tuesday had waived their right to appear before a judge. Those who did not will face one and will be held for 96 hours before being deported, she said.

Rima Hassan, a French member of the European Parliament who is of Palestinian descent, was also among the passengers on board the Madleen. She has previously been barred from entering Israel because of her opposition to Israeli policies toward the Palestinians. It was not clear whether she was being immediately deported or detained.

French Foreign Minister Jean-Noel Barrot said Tuesday that one of the detained French activists signed an expulsion order and will leave Israel on Tuesday for France. The other five refused. He said all the activists received consular visits.

Sergio Toribio, a Spanish activist who was deported, slammed Israel’s actions after he arrived in Barcelona.

“It is unforgivable, it is a violation of our rights. It is a pirate attack in international waters,” he told reporters.

Questions over a breach of international law

On Monday, Adalah, the rights group, said that Israel had “no legal authority” to take over the ship, because the group said it was in international waters and it was headed not to Israel but to the “territorial waters of the state of Palestine.”

“The arrest of the unarmed activists, who operated in a civilian manner to provide humanitarian aid, amounts to a serious breach of international law,” Adalah said in a statement.

Amnesty International said Israel was flouting international law with the naval raid and called on Israel to release the activists immediately and unconditionally.

Israel said its actions were consistent with international law.

Israel viewed the ship as a publicity stunt, calling it the “selfie yacht.” Israeli officials said that the flotilla was bringing “meager” aid with what amounted to less than a truckload of goods.

A longstanding blockade of Gaza

Israel and Egypt have imposed varying degrees of a blockade on Gaza since Hamas seized power from rival Palestinian forces in 2007. Israel says the blockade is needed to prevent Hamas from importing arms, while critics say it amounts to collective punishment of Gaza’s Palestinian population.

During the 20-month-long war in Gaza, Israel has restricted and sometimes blocked all aid into the territory, including food, fuel and medicine. Experts say that policy has pushed Gaza toward famine. Israel says Hamas siphons off the aid to bolster its rule.

Hamas-led militants killed around 1,200 people, mostly civilians, in the Oct. 7 attack that ignited the war and took 251 hostages, most of whom have since been released in ceasefire agreements or other deals. Hamas is still holding 55 hostages, more than half of them believed to be dead.

Israel’s military campaign has killed more than 54,000 Palestinians, according to the Gaza Health Ministry, which doesn’t distinguish between civilians and combatants but has said that women and children make up most of the dead.

The war has destroyed vast areas of Gaza and displaced around 90% of the territory’s population, leaving people there almost completely dependent on international aid.
