Israel-Gaza war: US and UK spy chiefs ‘working ceaselessly’ for ceasefire deal – as it happened

3.00pm BST

Closing summary

• Israeli military strikes across the Palestinian Gaza Strip killed at least 61 people in the space of 48 hours, local medics said on Saturday, as Israeli forces battled Hamas-led militants in the territory. Eleven months into the war, numerous rounds of diplomacy have so far failed to clinch a ceasefire deal to end the conflict and bring the release of Israeli and foreign hostages held in Gaza as well as many Palestinians jailed in Israel.

• At least 13 Palestinians were killed and 15 wounded in Israeli strikes on a school sheltering refugees and a residential building in Gaza, the Palestinian Authority’s official news agency reported early on Saturday. Wafa said at least eight of the dead were in refugee tents at Halima al-Sa’diyya school in Jabalia, northern Gaza , Reuters reports.

• British and American spy chiefs have said they are together “working ceaselessly” for a ceasefire and hostage deal in Gaza , in a rare public statement. MI6 chief Sir Richard Moore and CIA director Bill Burns said the two agencies have “exploited our intelligence channels to push hard for restraint and de-escalation” in the Middle East, PA Media reported.

• US secretary of state Antony Blinken said it was incumbent on both Israel and the Palestinian Islamist group Hamas to make concessions to reach a deal. On Saturday, senior Hamas official Hossam Badran said the group had made no new demands and remained committed to a 2 July proposal put forward by the United States, accusing Israeli prime minister Benjamin Netanyahu of attaching new conditions that would not end the war. Netanyahu says it was Hamas that introduced unacceptable conditions.

• Israeli soldiers killed an American woman demonstrating against settlements in the West Bank on Friday, according to a witness who said she was shot while posing no threat to Israeli forces and during a moment of calm after clashes earlier in the afternoon. Two Palestinian doctors said 26-year-old Aysenur Ezgi Eygi of Seattle was shot in the head. The US government confirmed Eygi’s death but did not say whether the recent graduate of the University of Washington, who was also a Turkish citizen, had been shot by Israeli troops, AP reported.

• At least 40,939 Palestinians have been killed and 94,616 others injured in Israel’s military offensive on Gaza since 7 October , Gaza’s health ministry said on Saturday.

• The launch of a major humanitarian appeal for Gaza by the Disasters Emergency Committee (DEC) is being delayed by the BBC, it has emerged. The corporation said the appeal did not meet all the established criteria for a national appeal, but the possibility of broadcasting an appeal was “under review”. Other channels have agreed to broadcast an appeal.

• CIA director William Burns, the chief US negotiator trying to help secure a ceasefire in Gaza and the release of hostages by Hamas , said a more detailed proposal on the ceasefire would be made in the coming days. “We will make this more detailed proposal, I hope in the next several days, and then we’ll see,” Burns said at an FT event in London on Saturday.

• The UK decision to suspend some arms exports to Israel has bolstered the case for Congress to follow the example of its ally, US campaigners for a ban have said. The campaigners are pressing the US Senate and the house to pass a joint resolution of disapproval blocking authorisation for an unprecedented $20bn (£15.2bn) weapons sale. The massive transfer was notified to Congress last month when it was in recess.

• Israeli forces battled Hamas-led militants in the Zeitoun suburb of Gaza City , where residents said tanks have been operating for more than a week, as well as in eastern neighbourhoods of Khan Younis and in Rafah, near the border with Egypt, where residents said Israeli forces blew up several houses.

• Residents of Khan Younis and displaced families from Rafah continued to crowd medical facilities, bringing their children to be vaccinated against polio . The UN agency for Palestinian refugees said at least 160,000 children received the drops on Thursday in southern areas of Gaza, where medical staffers began the second stage in the huge immunisation campaign.

That’s all from me, Tom Ambrose, and the Israel-Gaza live blog for today. Thanks for following along.

Iran still planning to retaliate for killing of Hamas leader - MI6

The head of Britain’s MI6 foreign spy agency Richard Moore said he believed that Iran was still planning to retaliate for the killing of Hamas leader Ismail Haniyeh, which took place in Tehran in late July and which Iran blames on Israel.

“I suspect they will try and we won’t be able to let our guard down for the type of activity that the Iranians might try and prosecute in that direction,” Moore said when asked about whether Iran would retaliate at an FT event on Saturday.

US secretary of state Antony Blinken said it was incumbent on both Israel and the Palestinian Islamist group Hamas to make concessions to reach a deal.

On Saturday, senior Hamas official Hossam Badran said the group had made no new demands and remained committed to a 2 July proposal put forward by the United States, accusing Israeli prime minister Benjamin Netanyahu of attaching new conditions that would not end the war.

Netanyahu says it was Hamas that introduced unacceptable conditions.

Despite the deadlock, the United Nations, in collaboration with local health authorities, has pursued a campaign to vaccinate 640,000 children in Gaza after its first polio case in around 25 years. Limited pauses in the fighting have allowed the campaign to proceed.

UN officials said they were making progress, having reached over half of the children needing the drops in the first two stages in the southern and central Gaza Strip.

On Sunday, the campaign will move to the northern Gaza Strip. A second round of vaccination will be required four weeks after the first.

Israeli strikes in Gaza kill 61 people

Israeli military strikes across the Palestinian Gaza Strip killed at least 61 people in the space of 48 hours, local medics said on Saturday, as Israeli forces battled Hamas-led militants in the territory.

Eleven months into the war, numerous rounds of diplomacy have so far failed to clinch a ceasefire deal to end the conflict and bring the release of Israeli and foreign hostages held in Gaza as well as many Palestinians jailed in Israel.

An Israeli airstrike in on the Halima al-Sa’diyya school compound serving as a shelter for displaced people in the Jabalia urban refugee camp killed at least eight people and wounded 15 others, medics said.

The Israeli military said the strike had targeted a Hamas command centre inside the compound. It accused Hamas of repeatedly exploiting civilians and civilian infrastructure for military purposes, an allegation Hamas denies.

Five more people were killed in a strike on a house in Gaza City.

CIA director William Burns, the chief US negotiator trying to help secure a ceasefire in Gaza and the release of hostages by Hamas, said a more detailed proposal on the ceasefire would be made in the coming days.

“We will make this more detailed proposal, I hope in the next several days, and then we’ll see,” Burns said at an FT event in London on Saturday.

Israeli soldiers killed an American woman demonstrating against settlements in the West Bank on Friday, according to a witness who said she was shot while posing no threat to Israeli forces and during a moment of calm after clashes earlier in the afternoon.

Two Palestinian doctors said 26-year-old Aysenur Ezgi Eygi of Seattle was shot in the head. The US government confirmed Eygi’s death but did not say whether the recent graduate of the University of Washington, who was also a Turkish citizen, had been shot by Israeli troops, AP reported.

The White House said it was “deeply disturbed” by the killing of a US citizen and called on Israel to investigate what happened. The Israeli military said it was looking into reports that troops had killed a foreign national while firing at an “instigator of violent activity” in the area of the protest.

The killing came amid a surge of violence in the West Bank since the Israel-Hamas war began in October, with increasing Israeli raids, attacks by Palestinian militants on Israelis, attacks by Israeli settlers on Palestinians and heavier military crackdowns on Palestinian protests. More than 690 Palestinians have been killed, according to Palestinian health officials.

Also Friday, Israeli troops shot and killed a 13-year-old Palestinian girl, Bana Laboom, in her village outside the West Bank town of Nablus, Palestinian health officials said.

The Israeli military said on Saturday that an “initial inquiry indicates” security forces had been deployed to disperse a riot involving Palestinian and Israeli civilians that “included mutual rock hurling.” The security forces had fired shots in the air, the military said.

“A report was received regarding a Palestinian girl who was killed by shots in the area. The incident is under review,” the military added.

US and UK spy chiefs 'working ceaselessly' for ceasefire deal

British and American spy chiefs have said they are together “working ceaselessly” for a ceasefire and hostage deal in Gaza, in a rare public statement.

MI6 chief Sir Richard Moore and CIA director Bill Burns said the two agencies have “exploited our intelligence channels to push hard for restraint and de-escalation” in the Middle East, PA Media reported.

In a joint article penned for the Financial Times, the spymasters wrote:

Our services are working ceaselessly to achieve a ceasefire and hostage deal in Gaza, which could end the suffering and appalling loss of life of Palestinian civilians and bring home the hostages after 11 months of hellish confinement by Hamas.

The pair said Burns in particular had played a “hands-on role” in negotiations in Egypt, bringing together opposing parties to broker a hostage and ceasefire deal in August.

The UK and US have largely acted in lockstep with their approach to the conflict in Gaza, but this week Keir Starmer’s Government diverted from this approach, announcing it would suspend some arms export licences to Israel.

Reports soon followed of US officials privately warning the British Government against the move, though UK ministers have publicly insisted it has not affected the relationship.

At least 40,939 Palestinians have been killed and 94,616 others injured in Israel’s military offensive on Gaza since 7 October , Gaza’s health ministry said on Saturday.

The launch of a major humanitarian appeal for Gaza by the Disasters Emergency Committee (DEC) is being delayed by the BBC, it has emerged.

The corporation said the appeal did not meet all the established criteria for a national appeal, but the possibility of broadcasting an appeal was “under review”. Other channels have agreed to broadcast an appeal.

Insiders at the DEC, the BBC and aid agencies said they were dismayed at the delay. Some have accused the BBC of “blocking” the appeal because the corporation fears a backlash from supporters of Israel in its war with Hamas. One senior NGO figure said that staff were “furious” at the BBC’s position.

The DEC has three criteria for launching an appeal. The scale and urgency of the disaster must merit swift international humanitarian assistance. Agencies must be able “to provide effective and swift humanitarian assistance at a scale to justify a national appeal” and there must be “evidence of existing public sympathy for the humanitarian situation” or “the likelihood of significant public support should an appeal be launched”. It is understood that the second criteria, regarding delivery of aid, is the focus of discussions.

The DEC is an umbrella organisation of 15 leading UK aid charities that raises funds for humanitarian disasters. It publicises its appeals through broadcasts on major networks and adverts in the press.

Pressure grows on US over arms exports to Israel

The UK decision to suspend some arms exports to Israel has bolstered the case for Congress to follow the example of its ally, US campaigners for a ban have said.

The campaigners are pressing the US Senate and the house to pass a joint resolution of disapproval blocking authorisation for an unprecedented $20bn (£15.2bn) weapons sale. The massive transfer was notified to Congress last month when it was in recess.

The US state department has said the UK decision to suspend arms sales has no bearing on US policy since the two countries have separate arms exports control regimes.

The degree of private anger with the US over the UK decision is contested, but one UK Foreign Office source said it was comparable to the US anger when David Cameron as foreign secretary said Israel should not have veto power on recognising Palestinian statehood.

The Biden administration’s anger is likely to increase if the UK decision becomes a potent talking point in the domestic US debates on suspension of arms sales.

Ayşenur Ezgi Eygi, a 26-year-old American activist killed while protesting in the occupied West Bank, was remembered by friends and former professors as a dedicated organiser who felt a strong moral obligation to bring attention to the plight of Palestinians.

“I begged her not to go, but she had this deep conviction that she wanted to participate in the tradition of bearing witness to the oppression of people and their dignified resilience,” said Aria Fani, a professor of Middle Eastern languages and cultures at the University of Washington (UW) in Seattle, which Eygi attended. “She fought injustice truly wherever it was.”

Fani, who had become close with Eygi over the last year, spoke to the Guardian on Friday afternoon, hours after news of her death sparked international outrage. Eygi was volunteering with the anti-occupation International Solidarity Movement when Israeli soldiers fatally shot her, according to Palestinian officials and two witnesses who spoke to the Associated Press. Two doctors told the AP she was shot in the head. The Israel Defense Forces (IDF) has said it was investigating a report that troops had killed a foreign national while firing at an “instigator of violent activity”, and the White House has said it was “deeply disturbed” by the killing and called for an inquiry.

Eygi, who is also a Turkish citizen and leaves behind her husband, graduated from UW earlier this year with a major in psychology and minor in Middle Eastern languages and culture, Fani said. She walked the stage with a large “Free Palestine” flag during the ceremony, Fani said.

Opening summary

Hello and welcome to the Guardian’s live coverage of the Israel-Gaza war and the wider crisis in the Middle East .

At least 13 Palestinians were killed and 15 wounded in Israeli strikes on a school sheltering refugees and a residential building in Gaza, the Palestinian Authority’s official news agency reported early on Saturday.

Wafa said at least eight of the dead were in refugee tents at Halima al-Sa’diyya school in Jabalia, northern Gaza, Reuters reports.

The Israeli army said in a statement it had “conducted a precise strike on terrorists who were operating inside a Hamas command and control centre … embedded inside a compound that previously served as the ‘Halima al-Sa’diyya’ School in the northern Gaza Strip”.

In a separate incident, five Palestinians were killed in an Israeli strike on a residential building in the Nuseirat camp in central Gaza.
