Israel-Gaza live updates: 'Constructive meeting' but 'gaps' remain: Israeli PM

The State Department is temporarily pausing new funding for the United Nations Relief and Works Agency for Palestine Refugees in the Near East while reviewing allegations that 12 UNRWA employees were involved in the Oct. 7 attack on Israel, according to State Department spokesman Matthew Miller.

Guterres "is horrified by this news" and asked the Commissioner-General of UNRWA, Philippe Lazzarini, to "investigate this matter swiftly and to ensure that any UNRWA employee shown to have participated or abetted what transpired on 7 October, or in any other criminal activity, be terminated immediately and referred for potential criminal prosecution," the secretary-general’s spokesperson said.

Lazzarini said he’s fired several staff members after Israel provided the agency "with information about the alleged involvement of several UNRWA employees" in the Oct. 7 attacks.

An investigation is underway, he said, warning that "any UNRWA employee who was involved in acts of terror will be held accountable, including through criminal prosecution."

The United Nations' top court decided Friday not to throw out South Africa's case accusing Israel of committing genocide against Palestinians in the war-torn Gaza Strip.

The International Court of Justice in The Hague is also set to announce its decision on "provisional measures," which could include ordering Israel to halt its military operations in Gaza.

"The court is acutely aware of the extent of the human tragedy that is unfolding in the region and is deeply concerned about the continuing loss of life and human suffering," ICJ president Joan Donoghue told the packed courtroom.

A final ruling on the genocide allegations, which Israel vehemently denies, is expected to take years.

The United Nations' top court is set on Friday to deliver its first interim ruling in the genocide case brought against Israel by South Africa.

The International Court of Justice in The Hague will not yet decide whether Israel has committed genocide -- a ruling that is expected to take years -- but instead will announce its decision on "provisional measures," which could include ordering Israel to halt its military operations in the neighboring Gaza Strip. The bar for ordering such measures is much lower than the final genocide ruling. For Friday, the court only has to decide if there is a "plausible" risk Israel is committing genocide against Gaza's 2.3 million Palestinian residents amid the war with Hamas, the militant group that rules the enclave. The panel of judges could also reject South Africa's case and shut down the trial -- a move that many legal experts say is unlikely.

Israel has vehemently denied the genocide allegations and can ignore any rulings from the ICJ , as it's done in the past. But the court's decisions would apply more pressure to Israel and its allies, including the United. States. The country has vehemently denied the genocide allegations.

At least 13 people were killed and 56 people were injured -- 21 of them critically – on Wednesday after a hit by "direct fire" struck the UNRWA Khan Yunis Training Center, where displaced people have been sheltering in Gaza, according to the UNRWA.

“There are 43,000 internally displaced people registered in this massively overcrowded UNRWA shelter, and all of them now find themselves at the epicentre of the war,” Thomas White, the director of UNRWA Affairs in Gaza, said in a statement. “Many have already been displaced multiple times and have nowhere else to go.”
