The lawsuit, brought by Democracy for the Arab World Now (DAWN) and the Taxpayer Alliance Against Genocide, comes as the Trump administration intensifies diplomatic efforts against the Hague-based court. Earlier this week, U.S. officials said the ICC posed a threat to U.S. sovereignty and pledged to expand sanctions, including travel restrictions on court personnel, while increasing pressure on the institution.

According to the complaint, the organizations contend that Trump’s February 2025 executive order has prevented them from engaging in activities protected under the First Amendment. They argue they have refrained from submitting information to the ICC and coordinating advocacy with individuals targeted by U.S. sanctions because of concerns they could face financial penalties or imprisonment.

The complaint also states that the sanctions extend to ICC judges and prosecutors as well as Palestinian human rights groups that called on the court to investigate allegations that the United States and Israel may have committed war crimes during the conflict in Gaza. Among those cited by the plaintiffs is Francesca Albanese, the United Nations special rapporteur on the occupied Palestinian territories, whose inclusion under the sanctions has, according to the lawsuit, further discouraged advocacy efforts.

“The Trump administration is using the blunt instrument of economic sanctions not only to punish human rights defenders but to police the political expression of millions of Americans,” Omar Shakir, executive director of Democracy for the Arab World Now, said in a statement.

Trump has consistently challenged the authority of the ICC, arguing that the court should not have jurisdiction over U.S. citizens, particularly members of the American military. His administration has maintained that international prosecutions involving U.S. personnel infringe upon national sovereignty.

The latest legal challenge follows a similar dispute during Trump’s first term. In 2020, his administration issued an executive order authorizing sanctions against ICC officials after the court pursued investigations that included possible crimes committed by U.S. forces in Afghanistan. A federal judge later blocked that order, finding it was likely to violate First Amendment protections. The sanctions were subsequently rescinded by President Joe Biden’s administration in 2021.

The Trump administration renewed its campaign against the ICC after the court issued an arrest warrant last year for Israeli Prime Minister Benjamin Netanyahu, a close U.S. ally. The renewed sanctions have also prompted separate legal action from three ICC judges, who have filed their own lawsuits challenging the measures.

Although ICC prosecutors opened an investigation in Afghanistan in 2020 that included alleged crimes involving U.S. forces, the court shifted its priorities in 2021. Since then, prosecutors have focused primarily on alleged crimes committed by Afghanistan’s former government and Taliban forces. According to the information provided, the court has not taken steps in recent years to investigate U.S. personnel.

The Trump administration’s latest announcement drew criticism from European partners that continue to support the ICC. On Tuesday, the European Union reaffirmed its commitment to the court and described it as an essential institution in efforts to combat impunity for serious international crimes.

European Commission spokesperson Anouar El Anouni said attacks or threats directed at the court, its elected officials, staff or individuals cooperating with its work were unacceptable. He added that the ICC does not target sovereign states and should not be regarded as a threat to their sovereignty.

The Dutch Foreign Ministry also reiterated its backing for the independence of international judicial institutions. In comments to Reuters, the ministry said it had taken note of the latest U.S. statements, describing Washington’s position as longstanding but expressing concern over what it called the increasingly hardened tone toward the court.

Spanish Foreign Minister Jose Manuel Albares said the Israeli charge d’affaires was called in to receive Madrid’s protest over what he described as the “unacceptable and intolerable” extension of the detention of Saif Abu Keshek, a Spanish citizen of Palestinian origin detained after Israeli forces intercepted the Global Sumud Flotilla in international waters near Greece last week.

An Israeli court has extended the detention of Abu Keshek and Brazilian activist Thiago Avila until Sunday, despite calls from international rights groups and foreign governments for their release. Israeli authorities have not filed formal charges against either activist.

The flotilla was the second maritime initiative in the past year aimed at challenging Israel’s blockade on Gaza, where shortages of food, medicine, water and fuel have intensified during the war between Israel and the Palestinian militant group Hamas.

Israeli forces intercepted the vessel and deported several activists to Europe while detaining Abu Keshek and Avila. Rights organizations have alleged the detainees were subjected to abuse while in custody, accusations Israeli authorities have denied.

The latest dispute underscores the widening rupture in relations between Spain and Israel since the outbreak of the Gaza conflict following Hamas’ Oct. 7, 2023 attack on Israel. Spanish Prime Minister Pedro Sanchez has repeatedly criticized Israel’s military campaign in Gaza and previously described it as a “genocide,” a characterization Israel strongly rejects.

Diplomatic ties deteriorated further after Spain formally recognized a Palestinian state in 2024, prompting Israel to recall its ambassador from Madrid. Spain later dismissed its own ambassador to Tel Aviv in March.

The diplomatic clash coincided with Madrid’s decision to honor Francesca Albanese, the United Nations special rapporteur on human rights in the occupied Palestinian territories, with the Order of Civil Merit.

Sanchez’s office said Albanese was recognized for her work documenting alleged violations of international law in Gaza. Albanese has repeatedly accused Israel of committing genocide during the conflict, allegations Israel denies, accusing critics of antisemitism.

The United States has imposed sanctions on Albanese, accusing her of “biased and malicious” criticism of both Washington and Israel. Spain has urged the European Commission to prevent the U.S. sanctions from being enforced within the European Union.

France and Germany have also criticized Albanese and called for her resignation over remarks referring to a “common enemy of humanity,” although Albanese has denied that the statement was directed at Israel.

On board was Swedish climate activist Greta Thunberg, along with 11 other crew members including Rima Hassan, a French Member of the European Parliament.

The vessel, operated by the Freedom Flotilla Coalition (FFC), carried a modest consignment of humanitarian aid—baby formula and rice—intended for civilians in Gaza, where the United Nations has warned of looming famine and mass displacement following months of war.

Seized in International Waters

According to a statement by the FFC, Israeli forces boarded the vessel at around 2:00 a.m. local time while it was still in international waters. A dramatic image shared by the coalition shows crew members sitting with hands raised, illuminated by intense spotlights.

Israeli authorities later confirmed the interception, stating that the crew was unharmed and en route to the Israeli port of Ashdod. “The ‘selfie yacht’ of the ‘celebrities’ is safely making its way to Israeli shores. The passengers are expected to return to their home countries,” wrote Israel’s Foreign Ministry on X (formerly Twitter).

The ministry added that the activists were “provided with sandwiches and water,” before bluntly concluding: “The show is over.”

Detentions and Defiance

The crew has reportedly been detained for interrogation. Rima Hassan posted on X, “The crew of the Freedom Flotilla was arrested by the Israeli army in international waters around 2 a.m.,” reaffirming their resolve by sharing the image of the crew’s detention.

In response, climate activist Greta Thunberg has yet to issue a direct statement, but supporters have called the seizure a blatant act of aggression against peaceful humanitarian efforts.

The Israeli Defense Ministry, however, defended the operation. Defense Minister Yoav Gallant said he had authorized the naval action to prevent what he labeled a “propaganda exercise supporting Hamas,” and confirmed that the intercepted aid would be routed through “official humanitarian channels.”

A Polarizing Mission

The Madleen’s voyage was never about scale—it carried only a symbolic amount of aid. But its intent was powerful: to highlight the severe humanitarian crisis in Gaza and challenge the legality and morality of Israel’s long-standing naval blockade.

Israel has enforced the blockade since 2007, after Hamas seized control of the coastal enclave. While Israel and its allies justify the measure as essential to preventing arms smuggling, critics argue it constitutes collective punishment against Gaza’s 2.3 million residents.

The situation has worsened dramatically since the October 7, 2023, Hamas-led attack on southern Israel, which killed over 1,200 people and led to the abduction of more than 250 individuals, according to Israeli sources.

In response, Israel launched a relentless military campaign that has killed over 54,000 Palestinians and displaced the vast majority of Gaza’s population, according to the Gaza Health Ministry.

International Support and Condemnation

The United Nations’ Special Rapporteur on the Palestinian Territories, Francesca Albanese, voiced strong support for the flotilla’s efforts.

In a post on X, she wrote, “Madleen’s journey may have ended, but the mission isn’t over. Every Mediterranean port must send boats with aid & solidarity to Gaza.”

Hamas condemned the seizure of the vessel, calling it “state terrorism” and saluting the activists for their “moral courage” and “solidarity with the oppressed.”

Meanwhile, Israeli Defense Minister Israel Katz revealed a provocative plan to show the detained activists videos of the October 7 Hamas attacks upon their arrival at Ashdod Port. “They need to see what they are defending,” he declared.

A Legacy of Flotillas

The interception of the Madleen echoes earlier flotilla efforts to challenge Israel’s blockade. The most infamous incident occurred in 2010, when Israeli commandos stormed the Mavi Marmara, a Turkish vessel, killing ten activists in an operation that strained Israel’s diplomatic ties with Turkey and ignited international outrage.

While this week’s operation ended without violence, it has once again exposed the raw tensions surrounding Gaza and the sharply diverging narratives around activism, security, and human rights.

The Freedom Flotilla Coalition said its mission is far from over. “We are not deterred. More ships will sail. The people of Gaza are not forgotten,” it said in a statement.

Aid Symbolism vs. Political Narrative

Though the Madleen carried only a symbolic quantity of aid, its interception has transformed it into a powerful political message. For supporters of Gaza, it represents solidarity against a prolonged humanitarian siege. For Israel, it is a line that cannot be crossed without invoking national security concerns.

This confrontation, once again, places the international community at a crossroads: should symbolic activism be embraced as a tool to spotlight suffering, or be condemned as a political stunt that complicates diplomacy and security?

Whatever the answer, the image of Greta Thunberg—more often associated with climate marches and UN podiums—being escorted by naval forces in a geopolitical flashpoint, has thrust the Gaza crisis back into the global spotlight.
