But the court still has not ruled on a genocide case against Israel filed last year.
The International Court of Justice issued an advisory opinion on Wednesday that Israel is legally obligated to work with the United Nations’ Palestinian relief agency to deliver aid into Gaza.
In its opinion, the ICJ rejected Israel’s justification for barring UNRWA, the UN Relief and Works Agency for Palestine, from operating in Israel in March, saying it was unable to prove that the agency was subject to “widespread infiltration” by Hamas.
While UNRWA still operates in Gaza, it has been unable to bring supplies into the enclave since the ban took effect.
“The occupying power may never invoke reasons of security to justify the general suspension of all humanitarian activities in occupied territory,” Judge Iwasawa Yuji said while delivering the opinion. “After examining the evidence, the court finds that the local population in Gaza Strip has been inadequately supplied.”
The ruling comes as top U.S. officials, including Vice President JD Vance, are in Israel to monitor the ceasefire between Israel and Hamas and lay the groundwork for improved humanitarian conditions in Gaza.
On Tuesday, Jared Kushner, who helped broker the deal, said there had been “surprisingly strong coordination” between the United Nations and Israel on delivering humanitarian aid into Gaza.
The ICJ, the United Nation’s top legal body, has no enforcement power. It ruled in January 2024 that South Africa’s claims that Palestinians are at risk of genocide were “plausible” but has not issued a ruling in that case.
The court’s opinion Wednesday passed in a vote of 10 to 1, with its Vice President Julia Sebutinde, who has previously ruled in favor of Israel, writing in her opinion that the court did not “sufficiently consider” UNRWA’s infiltration by Hamas.
Israel has long accused UNRWA employees of taking part in Hamas’ Oct. 7, 2023, attack. A UN investigation into the agency found that nine of its 13,000 workers “may have” participated in the attacks but no longer work for the agency.
Israel’s Foreign Ministry decried the ruling Wednesday in a post on X, writing that it “rejects the politicization of International Law.”
“Israel categorically rejects the ICJ’s ‘advisory opinion,’ which was entirely predictable from the outset regarding UNRWA,” the post read. “This is yet another political attempt to impose political measures against Israel under the guise of ‘International Law.’”
