THE HAGUE, Netherlands — The United Nations’ top court ordered Israel on Friday to immediately halt its military offensive in the southern Gaza city of Rafah, but stopped short of ordering a cease-fire for the enclave. Although Israel is unlikely to comply with the order, it will ratchet up the pressure on the increasingly isolated country.

Criticism of Israel’s conduct in the war in Gaza has been growing, particularly since it turned its focus to Rafah. This week alone, three European countries announced they would recognize a Palestinian state, and the chief prosecutor for another international court requested arrest warrants for Israeli leaders, along with Hamas officials.

Israeli Prime Minister Benjamin Netanyahu is also under some pressure at home to end the war, which was triggered when Hamas-led militants stormed into Israel, killing 1,200 people, most civilians, and taking roughly 250 hostage. Thousands of Israelis have joined weekly demonstrations calling on the government to reach a deal to bring the hostages home, fearing time is running out.

“The charges of genocide brought by South Africa against Israel at the International Court of Justice in the Hague are false, outrageous and morally repugnant,” Netanyahu’s government said in response to the ruling, maintaining its position that the military hasn’t and won’t target civilians.

South Africa was able to bring its case because it and Israel are signatories to the U.N.’s Genocide Convention, which includes a clause allowing the court to settle disputes over it.

Although the ruling is a blow to Israel’s international standing, the court doesn’t have a police force to enforce its orders. In another case on its docket, Russia has ignored the court’s 2022 order to halt its full-scale invasion of Ukraine.

The sharply focused decision sent a three-pronged message to Israel, ordering a halt to the Rafah offensive, access to Gaza for war crimes investigators, and a big and immediate increase of humanitarian aid to the region, parts of which are enduring famine.

Rafah is in the southernmost part of the Gaza Strip, on the border with Egypt, and over 1 million people sought refuge there in recent months after fleeing fighting elsewhere, with many of them living in teeming tent camps. Israel has been vowing for months to invade Rafah, saying it was Hamas’ last major stronghold, even as several allies warned that an all-out assault would spell disaster.

Israel started issuing evacuation orders about two weeks ago as it began operations on the edge of the city. Since then, the army says an estimated 1 million people have left as forces press deeper inside.

Rafah is also home to a critical crossing for aid, and the U.N. says the flow of aid reaching it has plunged since the incursion began, though commercial trucking has continued to enter Gaza.

The court ordered Israel to keep the Rafah crossing open, saying “the humanitarian situation is now to be characterized as disastrous.”

“This legally binding and very specific ruling leaves Israel with very little wiggle room,” said Reed Brody, a veteran human rights lawyer and prosecutor.

Benny Gantz, a popular centrist member of Netanyahu’s war cabinet, appeared to indicate that Israel would not change its course regarding Rafah.

“The State of Israel is committed to continue fighting to return its hostages and promise the security of its citizens — wherever and whenever necessary — including in Rafah,” he said.

“We will continue operating in accordance with international law wherever we might operate, while safeguarding to the best extent possible the civilian population. Not because of the ICJ, but because of who we are and the values we stand for.”

Balkees Jarrah, associate international justice director at Human Rights Watch, said the court’s order underscored the perilous situation of Palestinians in Gaza, but warned that it could be ignored if the international community doesn’t use whatever leverage it can on Israel.

“The ICJ’s decision opens up the possibility for relief, but only if governments use their leverage, including through arms embargoes and targeted sanctions, to press Israel to urgently enforce the court’s measures,” Jarrah said.

The court’s president, Nawaf Salam, read out the ruling as a small group of pro-Palestinian protesters demonstrated outside.

Fears the court expressed earlier this year about an operation in Rafah have “materialized,” the ruling said, and Israel must “immediately halt its military offensive” in the city and anything else that might result in conditions that could cause the “physical destruction in whole or in part” of Palestinians there.
