The International Court of Justice (ICJ) has received further interventions in South Africa’s genocide case against Israel, highlighting a stark divide among nations over the conflict in Gaza. The United States, Hungary, and Fiji submitted legal arguments on March 12 supporting Israel’s position, while Namibia, Iceland, and the Netherlands aligned with South Africa a day earlier. These filings bring the total number of intervening states to over a dozen.
The interventions were made under Article 63 of the ICJ’s statutes, which allows countries party to the 1948 Genocide Convention to present their own interpretation of the treaty during a dispute. The case, initiated by South Africa in December 2023, alleges that Israel’s military campaign in Gaza constitutes genocide, breaching the convention. Israel has consistently denied the allegation, stating its actions are lawful self-defense following the Hamas-led attack on October 7, 2023.
The US-led group urged a strict, narrow reading of the Genocide Convention. In its submission, Washington argued the case is legally flawed and that South Africa has not met the “extremely high threshold” for proving genocidal intent. These countries warned that expanding the definition could undermine international law. Conversely, the group backing South Africa, including Namibia, called for a broader interpretation that considers Israel’s overall conduct, the conditions in Gaza, and the war’s wider impact on the Palestinian population.
The conflict’s background remains central to the proceedings. Following the October 7 attack, which killed approximately 1,200 Israelis and saw over 250 taken hostage, Israel launched a military offensive in Gaza. According to Gaza’s health authorities, the operation has killed more than 72,000 Palestinians. A US-brokered ceasefire took effect in October 2025, but both Israel and Hamas accuse each other of violations, with over 650 Palestinians killed and 1,740 injured in subsequent months.
These interventions underscore deepening international divisions over the war. The ICJ’s eventual rulings on the genocide allegations and the interpretations of the convention will carry significant legal weight. The court’s process will continue with written submissions and oral hearings, with the interventions set to influence its deliberation on the provisional measures and the merits of the case. The filings reflect a global contest over the legal framework governing armed conflict and the definition of genocide.
