While mediators in Cairo persisted with efforts towards a Gaza truce, the United Nations agency for Palestinian refugees, UNRWA, came under renewed attack from Israel, whose military accused it of employing "over 450 terrorists" belonging to groups including Hamas.
UNRWA is at the center of efforts to provide humanitarian relief in Gaza, where aid groups warn of looming famine after nearly five months of war between Israel and the Islamist group.
Israel previously accused about a dozen UNRWA employees of involvement in the October 7 Hamas attack against southern Israel which began the war.
That attack resulted in the deaths of around 1,160 people, an AFP tally of official figures shows.
Israel's retaliatory offensive has killed 30,534 people, mostly women and children, according to the health ministry in the Hamas-ruled territory.
Phillipe Lazzarini, the head of UNRWA, has said that Israel provided no evidence against his former employees.
On Monday his agency, in a statement to AFP, said some UNRWA staff alleged "they were forced to confessions under torture and ill-treatment" while being asked about the October 7 attack.
Raped 'then killed'
Qatari and Egyptian mediators were meeting with United States and Hamas envoys — but no Israeli delegates so far — in Cairo for a second day of talks. They are aiming for a halt in fighting before the Muslim holy month of Ramadan starts early next week.
According to Israeli media reports, Israel's government has refused to send its delegation to Cairo, stating they had not been given a list of living hostages by Hamas.
However, Bassem Naim, a senior Hamas leader, told AFP from Cairo that details on the status of the prisoners "were not mentioned in any documents or proposals circulated during the negotiation process."
The plan under discussion is for a six-week truce, the exchange of dozens of remaining hostages for hundreds of Palestinian prisoners, and for more aid to enter Gaza.
Israel has said it believes 130 of the original 250 captives taken by Hamas during their attack remain in Gaza, but that 31 have been killed.
A UN report on Monday said there are "reasonable grounds to believe" rapes were committed during Hamas's attack and that hostages subsequently taken to Gaza have also been raped.
"In most of these incidents, victims first subjected to rape were then killed, and at least two incidents relate to the rape of women's corpses," the report said.
Shortly before the report's release, Israel said it was calling in its UN ambassador over what it said was an attempt by the body to "silence" information of sexual violence by Hamas.
The spokesman for UN Secretary-General Antonio Guterres denied trying to suppress the report, saying it "is being presented publicly today."
United States Vice President Kamala Harris — whose country provides billions of dollars in military aid to Israel — called for the truce deal to be accepted and criticised Israel in unusually strong language over insufficient aid deliveries into Gaza.
Harris said Israel "must open new border crossings" and "must not impose any unnecessary restrictions" on aid delivery.
Belgium on Monday sent a military transport plane to join an international operation to airdrop aid into Gaza also involving the United States, France and Jordan, officials said.
'We want to eat'
President Joe Biden faces acute pressure in an election year over his steadfast support for Israel and Gaza's soaring civilian death toll.
Harris, as well as Secretary of State Antony Blinken and National Security Advisor Jake Sullivan, were to meet Israel's former military chief Benny Gantz in Washington.
Gantz is a member of Netanyahu's war cabinet but also a centrist political rival of Netanyahu, who leads a coalition of religious and ultra-nationalist parties.
Itamar Ben Gvir, Netanyahu's national security minister, told members of his Jewish Power political party that Hamas was "deliberately delaying the talks."
He called for an end to the negotiations and movement instead to a "more powerful combat phase."
Polls have shown a drop in support for Netanyahu, whose failure to bring home the hostages has led to continuing protests.
Gaza's health ministry on Monday said bombardments and combat killed 124 more people within 24 hours.
Witnesses reported clashes in Gaza City's Zeitun neighborhood and the main southern city of Khan Younis, which has seen heavy fighting.
Khan Younis residents returned to find decomposing bodies lying in streets where homes and shops had been torn apart.
"We want to eat and live. Take a look at our homes. How am I to blame, a single, unarmed person without any income in this impoverished country?" asked Nader Abu Shanab, pointing to the rubble with blackened hands.
The Gaza war has sparked violence across the region, including near-daily exchanges of fire between Israeli forces and Lebanon's Hezbollah movement.
Indians wounded
On Monday, a foreign worker in northern Israel was killed and seven Indian workers were wounded in a missile strike near the Lebanese border, Israeli medics said.
Later, Hezbollah said three paramedics affiliated with the group were killed in an Israeli strike.
The violence came as United States envoy Amos Hochstein held talks with Lebanese officials in Beirut and called for a diplomatic solution.
Yemen's Iran-backed Houthi rebels, who since November have fired drones and missiles at numerous ships in the Red Sea area vital for world trade, claimed responsibility for another strike.
Their claim came after marine security firm Ambrey reported a Liberian-flagged vessel was targeted and reportedly struck off Yemen.
United Nations human rights chief Volker Turk cited Lebanon and Yemen as places where the Gaza war is having wider effect. He expressed deep concern "that in this powder keg, any spark could lead to a much broader conflagration."
