The UN representatives will kick off the proceedings at the International Court of Justice in The Hague, followed by a Palestinian submission.
Over the next five days, 38 countries will then address the 15-judge panel, including the US, China, France, Russia and Saudi Arabia. The League of Arab States, the Organization of Islamic Cooperation and the African Union will also make submissions.
The hearings are being held at the request of the UN General Assembly, which voted in favor of asking the World Court to weigh in on Israel’s legal obligations last December.
That resolution was put forward by Norway after Israel banned the UN agency for Palestinian refugees from operating in Israeli-controlled territory.
Meanwhile, medics in Gaza reported that Israeli forces have killed 23 Palestinians in predawn attacks, a day after killing at least 53 people across the Strip.
At least 52,243 Palestinians have been confirmed killed and 117,639 wounded in Israel’s war on Gaza since it began 18 months ago. The Gaza Government Media Office updated the death toll to more than 61,700, saying thousands of people missing under the rubble are presumed dead.
