The head of the UN agency for Palestinian refugees is set to defend his organization's work Monday at the General Assembly, after crippling backlash over accusations some employees were involved in Hamas's surprise October 7 attack on Israel.

Philippe Lazzarini warned in a letter to the General Assembly's president that the UNRWA is at a "breaking point" as donors freeze funding, Israel exerts pressure to dismantle the agency and humanitarian needs soar.

A US envoy said Monday that a diplomatic solution was key to ending nearly five months of intensifying hostilities between Lebanon's Hezbollah and Israel after the eruption of the Israel-Hamas war.

Israel and the Iran-backed Hezbollah movement have been exchanging near-daily fire since October, raising fears all-out conflict could spread across the region.

Israeli troops on Monday blew up the home of a Palestinian accused of killing a British-Israeli woman and her two daughters in the occupied West Bank last year.

The apartment of Moaz al-Masry, who was killed by Israeli forces following the April 7 attack, was demolished in the early hours, Palestinian witnesses and the Israeli military told AFP.

The Palestinian Red Crescent Society said their medics treated about 15 people after Israeli forces fired tear gas during the raid on the West Bank city of Nablus.

Israel and the main Palestinian aid agency traded accusations Monday of "terrorism" and torture, after the United States stepped up pressure for a halt in fighting between Israeli troops and Hamas militants.

While mediators in Cairo persisted with efforts toward 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.

Tunisian civil society groups fear the government is planning to starve them of foreign funding under the pretext of fighting money laundering and terrorism.

President Kais Saied, who launched a sweeping power grab in 2021 and rules by decree, has accused many non-government organisations of serving "foreign agendas".

Under a draft law he supported, state authorities would have to approve all foreign funding for NGOs that operate in the North African country.

US Vice President Kamala Harris called Sunday for a proposed six-week ceasefire deal in the Israel-Hamas war to be accepted, while criticizing Israel over insufficient aid deliveries into Gaza.

"Given the immense scale of suffering in Gaza, there must be an immediate ceasefire for at least the next six weeks, which is what is currently on the table," Harris said during a speech in Selma, Alabama.

Moscow, Riyadh and several other OPEC+ members on Sunday announced extensions to oil production cuts first announced in 2023 as part of an agreement among oil producers to boost prices following economic uncertainty.

The plan to extend cuts to mid-2024 comes on top of previous cuts to both oil output and exports as some of the world's largest energy producers drive to push up market rates.

Saudi Arabia's energy ministry said it would cut its production by one million barrels per day (bpd) from April to June (Q2), while Russia announced 471,000 bpd of cuts in Q2.

As men searched for survivors beneath a Gaza home pummelled by an air strike, Rania Abu Anza gazed down on Sunday at two children who did not survive: her infant twins.

The Palestinian woman said she had gone through multiple rounds of fertility treatment to achieve her dream of becoming a mother, only to have it taken away by the carnage in the Gaza Strip.

"Who will call me mother from now on? Who will call me mother?" she said through tears on Sunday as she clutched her lifeless babies, the face of one still spattered with blood.

Mediators in Cairo made a renewed push for a Gaza ceasefire, but differences remained as fighting raged on Sunday between Israeli forces and Hamas militants in the Palestinian territory gripped by desperate food shortages.

Witnesses told AFP that an Israeli strike hit an aid truck in central Gaza, killing several people, but the military denied the truck carried relief.

Turkish Cypriots will not sit at any negotiating table unless their sovereignty and equal status is recognised, the leader of the breakaway self-declared state in northern Cyprus told AFP Sunday.

This year marks the 50th anniversary since an Athens-backed coup aimed at uniting Cyprus with Greece triggered a Turkish invasion that divided the island in 1974.

Only Ankara recognises the statehood of the Turkish Republic of Northern Cyprus, which was proclaimed by Turkish Cypriot leaders in 1983.
