The US, Hungary and Fiji line up behind West Jerusalem, while over a dozen others back South Africa’s lawsuit
Several more states have moved to join the Gaza genocide case at the UN’s top court, deepening international divisions over Israel’s military campaign in the Palestinian enclave, according to the International Court of Justice (ICJ).
The case, brought by South Africa in December 2023 amid a deteriorating humanitarian crisis in Gaza as a result of Israel’s offensive, accuses the Jewish state of breaching the 1948 UN Genocide Convention. Since then, more than a dozen countries have applied to join the proceedings.
In a statement on Friday, the ICJ said that Namibia, the US, Hungary and Fiji had each filed declarations of intervention on March 12 in the proceedings under Article 63, which allows states party to the Genocide Convention to set out their own interpretation of the treaty when it is in dispute. Iceland and the Netherlands lodged similar declarations a day earlier.
South Africa argues that Israel’s conduct in Gaza – including mass killing, widespread destruction and the creation of conditions of life threatening the survival of Palestinians – amounts to genocide. Israel denies the accusation and insists its campaign is a legitimate act of self-defense against Hamas following the October 7 attack.
The US, Hungary and Fiji have submitted legal arguments backing Israel’s position and urging a strict reading of the Genocide Convention, warning that lowering the bar for proving genocidal intent could undermine international law. Washington characterized the lawsuit as legally flawed and urged the ICJ to reject the genocide allegation, arguing that the extremely high threshold for proving genocidal intent has not been met.
Namibia, Iceland and the Netherlands have joined more than a dozen countries that have aligned themselves with South Africa, calling for a broader interpretation of the Genocide Convention that considers Israel’s overall conduct, conditions in Gaza and the wider impact of the war.
The Gaza war was triggered by a Hamas raid into Israel on October 7, 2023, when militants killed around 1,200 people and took more than 250 hostage. West Jerusalem responded with a blockade, airstrikes and a ground operation in Gaza that has killed over 72,000 Palestinians, according to the enclave’s health officials.
Despite a US-brokered ceasefire in October 2025, over 650 Palestinians have been killed and more than 1,740 injured since then, with Israel and Hamas accusing each other of routinely violating the agreement.
