Israel claims to have the leader of Hamas holed up in his Gaza City bunker.
Yahya Sinwar has led Hamas since 2017, having joined its ranks in the early 1980s.
Believed to be the architect of the 7 October attacks, he is Israel’s most wanted – a “dead man walking”, according to Prime Minister Benjamin Netanyahu, who claims to have him “surrounded and isolated”.
He has spent more than 20 years in prison for killing both Israelis and fellow Palestinians suspected of collaborating with the other side.
The 61-year-old’s nicknames include “the face of evil”, “butcher of Khan Younis”, and “man of 12” – in reference to 12 suspected informers he is believed to have killed.
Granted fatwa by Hamas founder to kill collaborators
Sinwar was born in a refugee camp in Khan Younis, southern Gaza, in 1962.
He studied Arabic at the Islamic University of Gaza, which was founded in 1978 by the two men who went on to set up Hamas almost a decade later.
There he became particularly close to one of them, the cleric Sheikh Ahmed Yassin.
Yassin and Mahmoud al-Zahar co-founded Hamas in 1987 as a Gaza-based political splinter group of the Muslim Brotherhood.
According to Israeli reports, Sinwar said Yassin granted him a fatwa (a ruling in Islamic law) to kill anyone suspected of collaborating with the Israelis.
He was first arrested for subversive activities in 1982. In prison, he met other key members of Hamas, including Salah Shehade, the former leader of its military wing the Qassam Brigades.
After being arrested and imprisoned again in 1985, he was put in charge of Hamas’s internal security branch, the Majd Force, which sought out and killed suspected Israeli spies.
Dr Ahron Bregman, a former Israeli army major – and now senior teaching fellow in war studies and the Arab-Israeli conflict at King’s College London, said: “The Israelis tried for many years to recruit him as a collaborator himself, offering him massive incentives.
“But it never worked with Sinwar. In fact he became notorious for killing Palestinians suspected of collaborating.”

Analysed: Hamas leader Yahya Sinwar ‘surrounded in his bunker’
Learnt fluent Hebrew in prison
In 1988 he helped abduct and kill two Israeli Defence Force soldiers, which saw him sentenced to 22 years in an Israeli prison.
Despite being incarcerated, Sinwar used the time to his advantage – learning fluent Hebrew to better understand his enemy and ascending to become leader of Hamas prisoners in Israel.
Dr Bregman says: “He would read Israeli newspapers on a daily basis. He understood them way better than they understood him – hence his ability to deceive them and catch them off guard by executing his military operation so effectively in October 2023.”
Fifteen years into his prison sentence, he went on Israeli television and spoke in Hebrew, calling for a truce with Hamas.
He was released in 2011 as part of the swap of more than 1,000 Palestinian prisoners for just one hostage Israeli soldier – Gilad Shalit.
Commenting on his imprisonment afterwards, Sinwar said: “They wanted the prison to be a grave for us. A mill to grind our will, determination and bodies.
“But thank God, with our belief in our cause we turned the prison into sanctuaries of worship and academies for study.”
Forced suspected informer to bury his own brother
Back in Gaza he continued to increase his influence among Hamas’s highest ranks.
He remained committed to his original task of unmasking and killing traitors – both Israeli collaborators and members of rival militant groups.
A former member of Israeli intelligence told the Financial Times that he once boasted about forcing a Hamas member suspected of informing for a competing faction to “bury his own brother alive… handing him a spoon to finish the job”.
In 2015 he is thought to have been involved in the torture and killing of fellow Hamas commander Mahmoud Ishtiwi.
He was accused of embezzlement and “moral crimes”, including alleged homosexual activity, with Sinwar thought to have orchestrated his murder over fears he could compromise the group.
Commenting on how he killed another collaborator, he told how he and a group of others blindfolded Ishitiwi and drove him to a makeshift grave, before strangling him with a kaffiyeh (Arabic male headdress) and burying him there.
The same year he is thought to have killed Ishtiwi, he was designated a terrorist by the US government.
He replaced Ismail Haniyeh as Hamas leader in early 2017 and was re-elected in 2021, later surviving an assassination attempt.
As leader he has increased the group’s use of force, stepping up protests and rocket fire at the Israeli border.
With his military background, he is seen as someone capable of uniting Hamas’s armed and political wings.
Dr Bregman describes him as a “man of few words” and a “natural leader… charismatic, secretive and manipulative”.
“He will be remembered as the architect of the 7 October attacks and the person who inflicted on the Israelis their most terrible disaster since the establishment of their state in 1948,” he adds.
Although his methods have been “barbaric”, Dr Bregman believes it will be seen, “from a Palestinian point of view, in spite of the terrible price they are paying now, as a great victory”.
“Sinwar has earned a place in the pantheon of great Palestinian leaders,” he adds.
Testimonies from people on the ground in Gaza, however, suggest his violent methods have left many of them disillusioned with Hamas.
With Israel’s promise to destroy Hamas and all of its leaders, Dr Bregman believes they will “get him in the end”.
But before then he could be offered safe passage to another country as part of political deal, as former Palestinian Liberation Organisation (PLO) leader Yasser Arafat was to Tunisia in 1982.
“Whatever his fate, there is no doubt Sinwar will go down in Palestinian history as a mythical figure,” Dr Bregan says.
A fire has ripped through a Russian missile depot in the Tver region deep inside the country after it was targeted in a Ukrainian drone attack, the defence ministry in Moscow has said.
Footage shows a second Ukrainian drone attack on the southwestern Russian region of Krasnodar also triggered a fire and caused a series of explosions.
Russia’s defence ministry has claimed its forces shot down 101 Ukrainian drones over Russian territory and occupied Crimea during the overnight attacks.
The drone strikes were carried out as Ukrainian leader Volodymyr Zelenskky said he is hoping to meet Donald Trump next week when he travels to the US – where he will present US President Joe Biden with a “victory plan” in relation to the war.
Meanwhile, Ukraine’s foreign minister said Russia appears to be planning strikes on Ukrainian nuclear facilities before the winter.
Posts on local Telegram channels said a Ukrainian drone attack struck an arms depot near the town of Toropets, in Russia’s Tver region – which is about 380 kilometres (240 miles) northwest of Moscow and about 500 kilometres (300 miles) from the Ukrainian border on Saturday.
Russian authorities closed a 100-kilometre (62-mile) stretch of a highway and evacuated passengers from a nearby rail station.
The depot appeared to be just miles from a Russian weapons arsenal storing missiles, bombs and ammunition in Tver that was struck by Ukrainian drones early Wednesday, injuring 13 people and also causing a huge fire.
Meanwhile, at least 1,200 people were evacuated from Russia’s southwestern Krasnodar region after an ammunition depot and missile arsenal were struck in the second drone attack overnight, the local governor has said.

Most of those evacuated were staying with friends and relatives, Veniamin Kondratyev, the governor of Krasnodar region, said on the Telegram messaging app.
There were no immediate reports of casualties in either Tver or Krasnodar.
Ukraine warning of attacks on nuclear sites
It comes as Kyiv is urging the International Atomic Energy Agency (IAEA) and Ukraine’s allies to establish permanent monitoring missions at the country’s nuclear plants as it warns they could be targeted in Russian attacks.
“In particular, it concerns open distribution devices at (nuclear power plants and) transmission substations, critical for the safe operation of nuclear energy,” foreign minister Andriy Sybiha wrote on X.
Meanwhile, the Ukrainian leader has said he plans to meet Republican presidential candidate Mr Trump on either Thursday or Friday next week.
During the trip, Mr Zelenskyy will present Mr Biden with a so-called victory plan as he hopes to bring about an end to the conflict.
The Ukrainian president has said the plan will include long-range striking capabilities and other weapons long sought by Kyiv, and will serve as the basis for any future negotiation with Russia.
He is also expected to push Washington to lift restrictions on long-range missile strikes inside Russia.
Mr Zelenskyy will attend sessions of the UN Security Council and General Assembly and also plans to meet vice president Kamala Harris, the Democratic candidate in this year’s US election, in separate meetings on 26 September.
The developments come as three sources have told Reuters that Iran did not include mobile launchers with the close-range ballistic missiles that Washington has accused Tehran of delivering to Russia for use against Ukraine.
The sources – a European diplomat, a European intelligence official and a US official – said it was not clear why Iran did not supply launchers with the Fath-360 missiles, raising questions about when and if the weapons will be operational.
At least 44 people have been killed in Israeli strikes on Lebanon and Gaza in the last 24 hours.
A strike on the Lebanese capital Beirut killed at least 31 people including three children and seven women, the country’s health minister Firas Abiad said.
Fifteen of the 68 wounded in the attack remain in hospital.
Ali Harake, the head of the rescue team searching through the rubble, told Sky News his team is still looking for between 17 and 18 missing people – though he fears none have survived.

It is understood two apartment blocks in a densely populated southern neighbourhood collapsed in the strike – the deadliest attack on Beirut in decades.
Top Hezbollah commanders are believed to have been meeting in the basement of one of the buildings.

Hezbollah has confirmed two of its senior commanders, Ibrahim Aqil and Ahmed Wahbi, died in the strike while an Israeli military spokesperson said that at least 16 Hezbollah militants were killed.
Wahbi oversaw the military operations of the Radwan special forces – a commando unit that seeks to infiltrate and carry out attacks in Israel – until early 2024. Aqil was also a top commander for the Iran-backed group.

The Palestinian militant group Hamas has described the killing of Aqil as a “crime” and a “folly”, adding Israel will “pay the price”.
Meanwhile, at least 13 people have been killed in Israeli strikes on Gaza City, according to a local report.
The strikes are believed to have hit several schools sheltering displaced people in the southern part of the city.
The strikes come after Hezbollah launched one of its most intense bombardments of northern Israel in nearly a year of fighting, largely targeting Israeli military sites.
Israel’s Iron Dome missile defence system intercepted most of the Katyusha rockets.

Hezbollah said its latest wave of rocket attacks was a response to past Israeli strikes on southern Lebanon.
It came days after mass explosions of Hezbollah pagers and walkie-talkies killed at least 37 people, including two children. Some 2,900 others were wounded in the assault which has been widely attributed to Israel.
The Israeli airstrike in the southern suburbs of Beirut came as the Lebanese caretaker government was having an emergency meeting to discuss the previous two days of pager and radio explosions.
It caused yet more shock in a nation which considers itself battle-hardened after years of strife, disaster and wars.
But Lebanon has been truly rocked to its core by the string of attacks over the past few days.
“These are war crimes,” one Lebanese minister told us.
He’s been on the US most wanted list for more than forty years after being accused of being involved in the bombing of the US embassy and US marine barracks in 1983 which killed hundreds.
But the Hezbollahstronghold of Dahieh is a heavily populated crowded residential area and packed with shops, markets, and high-rise apartments.
The strike appeared to have flattened an entire block, flipping cars and leaving other vehicles covered in a heavy blanket of thick dust and rubble.
Several people could be seen in video footage filmed by neighbours, trapped under piles of rubble.
The Lebanese health authority keeps on updating the number of people killed in the strike, with the latest figures reaching 14.
There are more than 60 injured, with some of those believed to be in critical condition. Children are said to be among the dead, missing and injured.

Aftermath of IDF strike on Lebanon
‘Our actions speak for themselves’
The Israeli military immediately claimed success – saying that, along with Aqil, the strike had wiped out about 10 of his elite Radwan Force.
According to an IDF spokesman, who did not provide any evidence, Aqil’s team had been planning an attack into northern Israel similar to the Hamas attack on 7 October.
Both the prime minister and defence minister have vowed to restore security to the north of Israel so the 60,000 residents who have fled the cross-border attacks can return to their homes.
An estimated 120,000 Lebanese have also been forced out of their homes along the border.
The airstrike in the capital is the second in Beirut in two months – both, according to the IDF, targeted at senior Hezbollah commanders.
According to sources being quoted in Lebanese media, the Hezbollah group of senior leaders was meeting in an underground basement of a large housing block when the missile penetrated.

It is unlikely to be seen as a justifiable precision attack – or a “targeted strike”, as described by the Israeli military – if the Lebanese government ministers’ reactions are anything to go by.
We spoke to several as they arrived for their emergency cabinet meeting in the hour before the attack.
They were already incensed by the back-to-back coordinated booby trap explosions of communication devices across the country. Israel has yet to confirm or deny its involvement in the blasts.
Speaking about the pager and radio explosions across Lebanon earlier this week, the country’s environment minister and head of its disaster management committee Nasser Yassin said: “It’s genocidal, it’s indiscriminate and a violation of international humanitarian law and every other law.
“We have an insane leadership on the southern end of our borders who don’t want to be indicted by the International Court of Justice.”
The information minister Ziad Makary called the explosions of communication devices “a new crime… it’s a war crime and not something that would pass easily trying to kill three thousand or four thousand civilians as we see them”.
And Amin Salam, the economy minister, warned: “Things are escalating by the minute.
“There’s more tension, more provocation. We have been doing our best to get to a peaceful solution but the escalation is unprecedented.
“It’s an act of terror, regardless of who was targeted.”
Most intense border fighting in nearly a year
The airstrike in Beirut came after a marked increase in cross-border exchanges – the most intense in nearly a year.
The Israeli military said Hezbollah had spent the early part of the day firing nearly 200 rockets across the border into Israel.
Many of them were intercepted by the Iron Dome defence system.
This followed the Israeli bombing of more than 50 targets in the south of Lebanon overnight – which the IDF said hit launchers and weapons stores.
The Israeli military is suffering losses too – there were two funerals today for Israeli soldiers killed on their northern border – but it’s Hezbollah which seems to be paying a far heavier price right now.
Hezbollah unilaterally entered this latest war on 8 October, much to the frustration of Lebanon’s caretaker government, and a day after the Hamas attack on southern Israel.
Hezbollah have repeatedly said their actions are in support of Gaza and have continued to insist they will only stop once there’s a ceasefire.
But right now, the fighting group allied to Iran – and designated a terror group by the US and UK – appears to be very much on the backfoot after three attacks in four days.
Meanwhile, Israel is ploughing on despite the cries of indignation and condemnation from the international community.
