Audio analysis of footage of an Israeli attack on an aid worker convoy last month suggests that some of the shots were fired from as little as 12 metres away.
The Israel Defence Forces (IDF) has admitted killing the unarmed medics, saying that the convoy was acting “suspiciously”.
A spokesman told journalists in a 5 April briefing that an initial investigation had found there was “no firing from close distance” during the incident on 23 March.
Sky News has spoken to two independent audio forensic experts who analysed a 19-minute video of the attack filmed by Rifaat Radwan, one of the medics who was killed.
The expert analysis shared with Sky News suggests that the first gunshots heard in the video are likely 40-50 metres away from the phone recording the footage, but gunshots heard later are closer in distance – around 12-18 metres away.

In response to our findings, the IDF said a preliminary inquiry indicated that troops “opened fire due to a perceived threat following an encounter in the area”.
The shooting continues for six and a half minutes
The 19-minute video shows a convoy of marked ambulances and a fire engine travelling south along a road east of Rafah city.
A spokesman for the Israeli military initially claimed the emergency vehicles were travelling without any headlights or emergency signals, but the IDF later backtracked after the video disproved this claim. All vehicles visible in the convoy have their emergency lights on.
The video below shows the first gunshots fired during the attack.
After analysing the video, two audio forensic analysts told Sky News that “multiple shooters” were likely involved in the incident and “over 100 gunshots” were fired.
Audible gunshots are first heard 13 minutes and 35 seconds into the video, shortly after the convoy arrives at the scene of an earlier attack. The shooting continues for six and a half minutes.
Professor Rob Maher from Montana State University, an audio forensics expert working as an independent consultant, said: “The first few audible gunshots are likely 40-50 metres away from the (phone) microphone, based upon the crack-pop acoustic sequence and an assumption about the bullet speed.
“With so many audible gunshots, it seems likely that there were many firearms involved, and that those shooters were at different locations at different times during the many minutes of shooting.”
Most bullets travel faster than the speed of sound, this is called ‘supersonic’.
When a supersonic bullet is fired, the first sound you hear is the sharp ‘crack’ made by the bullet’s shockwave. After that, you hear the ‘bang’ from the gun firing, or muzzle blast. This second sound travels more slowly – at the speed of sound.
The time between the ‘crack’ and the ‘bang’ tells you how far away the gun is from the microphone. If the gun is far away, there’s a bigger gap between the two sounds. If it’s close, the gap is much shorter.
Another expert, Steven Beck of Beck Audio Forensics, estimated the distance of the first few gunshots to “around 40 metres”.
He added that the first audible shots are “most likely military rifles or carbines firing supersonic bullets that pass close to the recorder – meaning they are being fired at”.

Both forensic audio experts told us that as the video continues, the gunshots appear much closer – at a distance ranging between 12 and 18 metres. They explain that the “crack-bang” timing reduces in comparison to the start of the gunfire – indicating that the distance shortens.
Mr Beck said at the end of the video “there are more shockwaves followed by muzzle blasts. The shooter(s) at these times is much closer, with distances of 12m – 18m”.
Due to the overlapping gunshots heard in the video, from the audio it is not currently possible to rule out whether gunshots were fired back.
Prior to the attack, the ambulance from which the video is filmed had been searching for a group of paramedics who reported that they had been attacked by Israeli troops.
The ambulance travelled from southern Rafah up to the coast, before performing a U-turn and joining a convoy of other emergency vehicles.
The shooting began as the convoy arrived at the scene of the first attack.
In a statement to Sky News, the IDF said it is “conducting an inquiry into the incident, which took place in a combat zone, to uncover the truth.
“All the claims raised regarding the incident will be examined and presented in a detailed and thorough manner for a decision on how to handle the event.”
The IDF also says that six of the individuals killed were later identified as “Hamas terrorists”, though no evidence has been provided to support this claim.

“Terrible”, “weird”, “peculiar” and “baffling” – some of the adjectives being levelled by observers at the Donald Trump administration’s peace plan for Ukraine.
The 28-point proposal was cooked up between Trump negotiator Steve Witkoff and Kremlin official Kirill Dmitriev without European and Ukrainian involvement.
It effectively dresses up Russian demands as a peace proposal. Demands first made by Russia at the high watermark of its invasion in 2022, before defeats forced it to retreat from much of Ukraine.

Ukrainian support for peace plan ‘very much in doubt’
The suspicion is Mr Witkoff and Mr Dmitriev conspired together to choose this moment to put even more pressure on the Ukrainian president.
Perversely, though, it may help him.
There has been universal condemnation and outrage in Kyiv at the Witkoff-Dmitriev plan. Rivals have little choice but to rally around the wartime Ukrainian leader as he faces such unreasonable demands.
The genesis of this plan is unclear.
Was it born from Donald Trump’s overinflated belief in his peacemaking abilities? His overrated Gaza ceasefire plan attracted lavish praise from world leaders, but now seems mired in deepening difficulty.
The fear is Mr Trump’s team are finding ways to allow him to walk away from this conflict altogether, blaming Ukrainian intransigence for the failure of his diplomacy.
Mr Trump has already ended financial support for Ukraine, acting as an arms dealer instead, selling weapons to Europe to pass on to the invaded democracy.
If he were to take away military intelligence support too, Ukraine would be blind to the kind of attacks that in recent days have killed scores of civilians.
Europe and Ukraine cannot reject the plan entirely and risk alienating Mr Trump.
They will play for time and hope against all the evidence he can still be persuaded to desert the Kremlin and put pressure on Vladimir Putin to end the war, rather than force Ukraine to surrender instead.
This is the first time the G20 summit is being hosted on African soil.
Heads of state from 15 countries across Europe, Asia and South America are expected to convene in South Africa’s economic capital, Johannesburg, under the banner of “solidarity, equality and sustainability.”
The summit is facing challenges from the Oval Office as US President Donald Trump boycotts the event, where the G20 leadership is meant to be handed over to him by South African President Cyril Ramaphosa.
The US has also warned South Africa against issuing a joint declaration at the end of the summit. The challenges to South Africa’s G20debut are also domestic.

Nationwide civic disobedience has been planned by women’s rights charities, nationalist groups and trade unions – all using this moment to draw the government’s attention to critical issues it has failed to address around femicide, immigration and high unemployment.
But a key symbolic threat to the credibility of an African G20 summit themed around inclusivity is the continued exclusion and marginalisation of its oldest communities.
“There is a disingenuous thread that runs right through many of these gatherings, and the G20 is no different”, Khoisan Chief Zenzile tells us in front of the First Nations Heritage Centre in Cape Town, “from any of them”.

“I am very concerned that the many marginalised sections of society – youth, indigenous people, are not inside the front and centre of this agenda,” he added.

As we speak, the sounds of construction echo around us. We are standing in a curated indigenous garden as South Africa’s Amazon headquarters is being built nearby.
After years of being sidelined by the government in a deal that centres around construction on sacred Khoisan land, Chief Zenzile said he negotiated directly with the developers to build the heritage centre and sanctuary as a trade-off while retaining permanent ownership of the land.
“There are many people who like to fetishise indigenous people who want to relegate us to an anthropoid state, as if that is the only place we can, as if we don’t have the tools to navigate the modern world,” he says when I ask about modern buildings towering over the sacred land.
“That is the most ridiculous notion – that the entire world must progress and we must be relegated to a state over which we have no agency.”
An hour and a half from Cape Town’s centre, Khoi-San communities have seized 2,000 hectares of land that they say historically belongs to them.
Knoflokskraal is a state where they exercise full agency – filling in the infrastructural gaps around water and electricity supply that the provincial government will not offer to residents it categorises as “squatters”.
“We are – exactly today – here for five years now,” Dawid De Wee, president of the Khoi Aboriginal Party, tells us as he gives us a tour of the settlement. “There are more or less around 4,000 of us.
“The calling from our ancestral graves sent us down here, so we had an urge to get our own identity and get back to our roots, and that was the driving motive behind everything we are here now to take back our ancestral grounds.”

Dawid says they have plans to expand to reclaim more swathes of land stolen from them by European settlers in the 1600s across the Cape Colony.
Land reform is a contentious issue in post-Apartheid South Africa, with a white minority still owning a majority of the land.
Indigenous land is even further down the agenda of reparations, and South Africa’s oldest communities continue to suffer from historic dispossession and marginalisation.
For many Khoi-San leaders, G20 represents the ongoing exclusion from a modern South African state.
They have not been invited to officially participate in events where “solidarity, equality and sustainability,” are being discussed without reference to their age-old knowledge.
Instead, we meet Khoi-San Queen Eloise at a gathering of tribal leaders from around the world on the most southwestern tip of Africa in Cape Point called the World Tribal Alliance.

“In order for us to heal, Mother Nature and Mother Earth is calling us, calling our kinship, to come together – especially as indigenous people because with indigenous people we are still connected to our lands, to our intellectual property we are connected to who we are,” Queen Eloise tells us.
“G20 is a politically-based gathering – they are coming together to determine the future of people politically.
“The difference is that we will seek what Mother Earth wants from us and not what we want to do with technology or all those things politically, but the depth of where we are supposed to go.”
A fierce warning from Britain’s defence secretary to Vladimir Putin to turn his spy ship away from UK waters or face the consequences was a very public attempt to deter the threat.
But unless John Healey backs his rhetoric up with a far more urgent push to rearm – and to rebuild wider national resilience – he risks his words ringing as hollow as his military.
The defence secretary on Wednesday repeated government plans to increase defence spending and work with NATO allies to bolster European security.

Instead of focusing purely on the threat, he also stressed how plans to buy weapons and build arms factories will create jobs and economic growth.
In a sign of the government’s priorities, job creation is typically the top line of any Ministry of Defence press release about its latest investment in missiles, drones and warships rather than why the equipment is vital to defend the nation.
I doubt expanding employment opportunities was the motivating factor in the 1930s when the UK converted car factories into Spitfire production lines to prepare for war with Nazi Germany.
Yet communicating to the public what war readiness really means must surely be just as important today.

Mr Healey also chose this moment of national peril to attempt to score political points by criticising the previous Conservative government for hollowing out the armed forces – when the military was left in a similarly underfunded state during the last Labour government.
A report by a group of MPs, released on the same day as Mr Healey rattled his sabre at Russia, underlined the scale of the challenge the UK faces.

It accused the government of lacking a national plan to defend itself from attack.
The Defence Select Committee also warned that Mr Healey, Sir Keir Starmer and the rest of the cabinet are moving at a “glacial” pace to fix the problem and are failing to launch a “national conversation on defence and security” – something the prime minister had promised last year.

The report backed up the findings of a wargame podcast by Sky News and Tortoise that simulated what might happen if Russia launched waves of missile strikes against the UK.
The series showed how successive defence cuts since the end of the Cold War means the army, navy and air force are woefully equipped to defend the home front.
But credible national defences also require the wider country to be prepared for war.
A set of plans setting out what must happen in the transition from peace to war was quietly shelved at the start of this century, so there no longer exists a rehearsed and resourced system to ensure local authorities, businesses and the wider population know what to do.

Mr Healey revealed that the Russian spy ship had directed a laser light presumably to dazzle pilots of a Royal Air Force reconnaissance aircraft that was tracking it.
“That Russian action is deeply dangerous,” he said.
“So, my message to Russia and to Putin, is this: We see you. We know what you are doing. And if Yantar travels south this week, we are ready.”
He did not spell out what this might mean but it could include attempts to block the Russian vessel’s passage, or even fire warning shots to force it to retreat.

However, any direct engagement could trigger a retaliation from Moscow.
For now, the Russian ship – fitted with spying equipment to monitor critical national infrastructure such as communications cables on the seabed – has moved away from the UK coast. It was at its closest between 5 and 11 November.
The military is still tracking its movements closely in case the ship returns.
