Israel strongly denied charges of genocide on Friday, telling the United Nations’ top court it was doing everything it could to protect the civilian population during its military operation in Gaza.

The International Court of Justice wrapped up a third round of hearings on emergency measures requested by South Africa, which says Israel’s military incursion in the southern city of Rafah threatens the “very survival of Palestinians in Gaza” and has asked the court to order a cease-fire.

Tamar Kaplan-Tourgeman, one of Israel’s legal team, defended the country’s conduct, saying it had allowed in fuel and medication to the beleaguered enclave.

“Israel takes extraordinary measures in order to minimize the harm to civilians in Gaza,” she told The Hague-based court.

A protester shouting “Liars” briefly interrupted Kaplan-Tourgeman’s final remarks. The hearing was paused for less than a minute while security guards escorted a woman from the public gallery.

South Africa told the court on Thursday that the situation in the beleaguered enclave has reached “a new and horrific stage” and urged judges to order a half to Israeli military operations. The court was holding a third round of hearings on emergency measures requested by South Africa since it first filed its genocide case at the end of last year.

According to the latest request, South Africa says Israel’s military incursion in Rafah threatens the “very survival of Palestinians in Gaza.” In January, judges ordered Israel to do all it can to prevent death, destruction and any acts of genocide in Gaza, but the panel stopped short of ordering an end to the military offensive. Judges will now deliberate on the request and are expected to issue a decision in the next weeks.

ICJ judges have broad powers to order a cease-fire and other measures, though the court doesn’t have its own enforcement apparatus. A 2022 order by the court demanding that Russia halt its full-scale invasion of Ukraine has so far gone unheeded.

Most of Gaza’s population of 2.3 million people have been displaced since fighting began.

The war began with a Hamas attack on southern Israel on Oct. 7 in which Palestinian militants killed around 1,200 people and took about 250 hostages. More than 35,000 Palestinians have been killed in the war, Gaza’s Health Ministry says, without distinguishing between civilians and combatants in its count.
