Hamas's Gaza chief 'eliminated', says Netanyahu - but military sources say they cannot confirm death

But Israeli military sources have said they are not yet able to confirm the death.

Hamas has also not yet confirmed the apparent killing of its leader.

Meanwhile, with Gaza on the brink of famine, the Palestinian ambassador to the United Nations broke down in tears as he spoke of the suffering of its people.

Riyah Mansour told the Security Council: "Children are dying of starvation. The images of mothers embracing their motionless bodies. Caressing their hair, talking to them, apologising to them, is unbearable."

He added: "I have grandchildren. I know what they mean to their families. And to see this situation over the Palestinians without us having hearts to do something is beyond the ability of any normal human being to tolerate. Flames and hunger are devouring Palestinian children. This is why we are so outraged as Palestinians everywhere."

The older sibling was the mastermind of the October 7 2023 attack, which killed 1,200 people in Israel, with around 250 others taken hostage into Gaza.

The attack triggered Israel's assault on Gaza which decimated the territory, with more than 53,000 people killed, mostly women and children, and over two million displaced, according to health officials, who do not distinguish between civilians and combatants in their tally of fatalities.

Yahya Sinwar was killed in a gun battle with Israeli troops in Gaza last October. His younger sibling was believed to have then become the head of Hamas's armed wing.

Speaking to the Knesset on Wednesday, Mr Netanyahu included Mohammed Sinwar in a list of Hamas leaders killed in Israeli strikes. Later, Israel Defence Forces (IDF) sources said they were not yet able to confirm the death.

The prime minister said: "We have killed tens of thousands of terrorists. We killed (Mohammed) Deif, (Ismail) Haniyeh, Yahya Sinwar and Mohammed Sinwar." He did not elaborate.

Mohammed Sinwar had reportedly been the target of an Israeli strike on a hospital in southern Gaza on 13 May and Mr Netanyahu said on 21 May that it was likely he had been killed.

The Israeli military had said it struck a Hamas command centre under the European Hospital in the Sinwars' hometown of Khan Younis, and it declined to comment on whether Sinwar was targeted or killed.

At least six people were killed in the strike and 40 wounded, Gaza's health ministry said at the time.

Sinwar rose through ranks

Like his older brother, Mohammed Sinwar joined Hamas after it was founded in the late 1980s as the Palestinian branch of the Muslim Brotherhood. He became a member of the group's military wing, known as the Qassam Brigades.

Sinwar rose through the ranks to become a member of its so-called joint chiefs of staff, bringing him close to its longtime commander, Deif, who was killed in a strike last year.

"In the last two days, we have been in a dramatic turn towards a complete defeat of Hamas," the Israeli leader told the Knesset.

Mr Netanyahu also spoke about how Israel was "taking control of food distribution", a reference to a new aid distribution system that has been criticised and boycotted by humanitarian groups and the UN.

One killed at site of aid hub

The development comes after one person was killed and 48 others injured when forces opened fire on a crowd that overwhelmed an aid hub in Gaza, according to local health officials.

Palestinians have become increasingly desperate for food after almost three months of Israeli border closures. A blockade has recently been eased.

Israeli ambassador criticises UN agencies

Danny Danon, Israel's ambassador to the United Nations, has criticised UN agencies facilitating aid in Gaza, accusing the international body, without evidence, of holding up aid at border crossings.

"As we speak, there are more than 400 trucks already on the other side of the fence, waiting to be distributed, but the UN has failed to pick them up," Mr Danon told reporters. "We opened the crossings. We provided safe routes for those truck. But the UN did not show up."

People broke through fences around the distribution site on Wednesday, and a journalist with the Associated Press said they heard Israeli tank and gunfire, and saw a military helicopter firing flares.

It was not yet known whether the death and injuries were caused by Israeli forces, private contractors or others.

The Israeli and US-backed Gaza Humanitarian Foundation, which set up the hub outside Rafah, said its military contractors had not fired on the crowd but "fell back" before resuming aid operations. Israel said its troops nearby had fired warning shots.

The UN and other humanitarian organisations have rejected the new system, saying it will not meet the needs of Gaza's 2.3 million people and allows Israel to use food to control the population.

Israel has vowed to seize control of Gaza and fight until Hamas is destroyed or disarmed and exiled, and until the militant group returns the last 58 hostages, including around a third thought to be still alive.

'This is a man-made catastrophe'

Meanwhile, a US trauma surgeon who has been working in Gaza urged the UN Security Council to not "claim ignorance" about the humanitarian devastation.

Dr Feroze Sidhwa said: "Let's not forget, this is a man-made catastrophe. It is entirely preventable. Participating in it or not allowing it to happen is a choice.

"This is a deliberate denial of conditions necessary for life: food, shelter, water and medicine."

The UN World Health Organization has documented around 700 attacks on healthcare facilities in Gaza during the war. Israel accuses Hamas of using hospitals as command centres and to hide fighters.
