The International Court of Justice (ICJ) has said Israel has a legal obligation to facilitate the delivery of humanitarian aid to the Gaza Strip by the UN and its entities to ensure the basic needs of Palestinian civilians there are met.
An advisory opinion from the UN's top court also said Israel had not substantiated its allegations that the UN agency for Palestinian refugees (Unrwa) lacked neutrality or that a significant number of its staff were members of Hamas or other armed groups.
The UN's chief said he hoped Israel would abide by the "very important decision".
But Israel rejected the ICJ's opinion as "political" and insisted it would not co-operate with Unrwa, which it has banned.
The opinion is non-binding, but it carries significant moral and diplomatic weight.
In December, the UN General Assembly asked the ICJ for an opinion on Israel's obligations, as an occupying power and a member of the UN, towards UN agencies and other international organisations operating in Gaza and the occupied West Bank, including East Jerusalem.
It came after the Israeli parliament passed laws banning any activity by Unrwa on Israeli territory and contact with Israeli officials.
