United Nations. The United Nations chief said Monday that the United Nations has offered to monitor any cease-fire in Gaza and demanded an end to the worst death and destruction he has seen in his more than seven-year tenure.

Secretary-General António Guterres said in an interview with The Associated Press that it’s “unrealistic” to think the UN could play a role in Gaza’s future, either by administering the territory or providing a peacekeeping force, because Israel is unlikely to accept a UN role.

But he said, “The UN will be available to support any cease-fire.” The United Nations has had a military monitoring mission in the Middle East, known as UNTSO, since 1948, and “from our side, this was one of the hypotheses that we’ve put on the table,” he said.

“Of course, we’ll be ready to do whatever the international community asked for us,” Guterres said. “The question is whether the parties would accept it, and in particular whether Israel would accept it.”

Israel’s military assault on Gaza, triggered by Hamas' attacks in southern Israel on Oct. 7, has stretched for 11 months, with recent cease-fire talks failing to reach a breakthrough and violence in the West Bank reaching new highs.

Stressing the urgency of a cease-fire now, Guterres said: “The level of suffering we are witnessing in Gaza is unprecedented in my mandate as secretary-general of the United Nations. I’ve never seen such a level of death and destruction as we are seeing in Gaza in the last few months.”

The war has killed over 40,900 Palestinians, according to Gaza’s Health Ministry. The ministry, part of Gaza’s Hamas government, does not differentiate between fighters and civilians in its count though it says about half of the dead have been women and children. Israel says at least 17,000 militants are among the dead.

The war has caused vast destruction and displaced around 90 percent of Gaza’s population of 2.3 million people, often multiple times.

Israel’s UN Ambassador Danny Danon reacted to Guterres' comments saying, “It is disappointing to see the UN advocate for a cease-fire without mentioning the hostages and without condemning Hamas.”

"A cease-fire cannot – and will not – take place so long as our remaining hostages taken from us on Oct. 7 remain in captivity in Gaza,” he said in a statement. “I urge the UN Security Council to urgently convene and condemn Hamas in the strongest possible terms and demand the release of all 101 hostages in Gaza.”

Israeli Prime Minister Benjamin Netanyahu and his government have accused the UN of being anti-Israel and have been highly critical of UN humanitarian operations in Gaza, including accusing UN workers of collaborating with Hamas. He also has voiced skepticism about peacekeeping missions, saying only Israel can protect itself.

Facing protests at home and increasing urgency from allies, Netanyahu has pushed back against pressure for a cease-fire deal and declared that “no one will preach to me.”

Looking beyond an agreement, Guterres stressed that a two-state solution to the decades-old Israeli-Palestinian conflict is not only viable, “it’s the only solution.”

The United States and others support Palestinian statehood in lands captured by Israel in the 1967 Mideast war, but Netanyahu, who is leading the most conservative government in Israel’s history, has opposed calls for a two-state solution.

Guterres asked rhetorically whether the alternative is viable.

“It means that you have 5 million Palestinians living there without any rights in a state,” he said. “Is it possible? Can we accept an idea similar to what we had in South Africa in the past?"

He was referring to South Africa’s apartheid system from 1948 until the early 1990s when its minority white population marginalized and segregated people of color, especially Black people.

“I do not think you can have two peoples living together if they are not in a basis of equality, and if they are not in a basis of respect -- mutual respect of their rights,” Guterres said. “So the two-state solution is, in my opinion, a must if we want to have peace in the Middle East.”

The Palestinians have circulated a draft UN resolution demanding that Israel end its “unlawful presence” in Gaza and the West Bank within six months. The proposed General Assembly resolution follows a ruling by the top United Nations court in July that said Israel’s presence in the Palestinian territories is unlawful and must end.

In the wide-ranging interview, the U.N. chief painted a grim global picture, saying, “Our world is in total disarray -- I would say in total chaos.”

Conflicts are spreading and the most dramatic ones like Ukraine and Gaza have no end in sight, he said. Climate change is having devastating effects and artificial intelligence is developing without serious guardrails.
