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.

It has been an extraordinary few hours which may well set the tone for a hugely consequential week ahead.
In the time that it took me to fly from London to Saudi Arabia, where President Donald Trump will begin a pivotal Middle East tour this week, a flurry of news has emerged on a range of key global challenges.
• On the Ukraine war: President Volodymyr Zelenskyy has said he is prepared to meet Russian President Vladimir Putin in Istanbul – this announcement came minutes after Trump urged Zelenskyy to agree to the meeting.
• On the China-US trade war: The White House says the two countries have agreed to a “trade deal”. China said the talks, in Geneva, were “candid, in-depth and constructive”.
All three of these developments represent dramatic shifts in three separate challenges and hint at the remarkable influence the US president is having globally.
This sets the ground for what could be a truly consequential week for Trump’s presidency and his ability to effect change.
On Ukraine, Putin held a late-night news conference at the Kremlin on Saturday at which he made the surprise proposal of talks with Zelenskyy in Istanbul this Thursday.
But he rejected European and US calls for an immediate ceasefire.
The move was widely interpreted as a delay tactic.
Trump then issued a social media post urging Zelenskyy to accept the Russian proposal; effectively to call Putin’s bluff.
The American president wrote: “President Putin of Russia doesn’t want to have a Cease Fire Agreement with Ukraine, but rather wants to meet on Thursday, in Turkey, to negotiate a possible end to the BLOODBATH. Ukraine should agree to this, IMMEDIATELY. At least they will be able to determine whether or not a deal is possible, and if it is not, European leaders, and the U.S., will know where everything stands, and can proceed accordingly! I’m starting to doubt that Ukraine will make a deal with Putin, who’s too busy celebrating the Victory of World War ll, which could not have been won (not even close!) without the United States of America. HAVE THE MEETING, NOW!!!”
“We await a full and lasting ceasefire, starting from tomorrow, to provide the necessary basis for diplomacy. There is no point in prolonging the killings. And I will be waiting for Putin in Türkiye on Thursday. Personally. I hope that this time the Russians will not look for excuses,” Zelenskyy wrote on X.
The prospect of Putin and Zelenskyy together in Istanbul on Thursday is remarkable.
It raises the possibility that Trump would want to be there too.

Israel’s war in Gaza
On Gaza, it’s been announced that US envoy Steve Witkoff will arrive in Israel on Monday to finalise details for the release of Idan Alexander, an Israeli-American hostage being held by Hamas.
The development comes after it was confirmed that Mr Witkoff has been holding discussions with Israel, Qatar and Egypt and, through them, with Hamas.
The talks focused on a possible Gaza hostage deal and larger peace discussions for a ceasefire.
Meanwhile, officials from the United States and China have been holding talks in Geneva, Switzerland, to resolve their trade war, which was instigated by Trump’s tariffs against China.
Late on Sunday evening, the White House released a statement claiming that a trade deal had been struck.
In a written statement, titled “U.S. Announces China Trade Deal in Geneva”, treasury secretary Scott Bessent said: “I’m happy to report that we made substantial progress between the United States and China in the very important trade talks… We will be giving details tomorrow, but I can tell you that the talks were productive. We had the vice premier, two vice ministers, who were integrally involved, Ambassador Jamieson, and myself. And I spoke to President Trump, as did Ambassador Jamieson, last night, and he is fully informed of what is going on. So, there will be a complete briefing tomorrow morning.”
Beijing Global Times newspaper quoted the Chinese vice premier as saying that the talks were candid, in-depth and constructive.
However, the Chinese fell short of calling it a trade deal.

In a separate development, US media reports say that Qatar is preparing to gift Trump a Boeing 747 from its royal fleet, which he would use as a replacement for the existing and aging Air Force One plane.
The Qatari government says no deal has been finalised, but the development is already causing controversy because of the optics of accepting gifts of this value.
Of all the fronts in Donald Trump’s trade war, none was as dramatic and economically threatening as the sky-high tariffs he imposed on China.
There are a couple of reasons: first, because China is and was the single biggest importer of goods into the US and, second, because of the sheer height of the tariffs imposed by the White House in recent months.
In short, tariffs of over 100% were tantamount to a total embargo on goods coming from the United States’ main trading partner. That would have had enormous economic implications, not just for the US but every other country around the world (these are the world’s biggest and second-biggest economies, after all).
So the truce announced on Monday by treasury secretary Scott Bessent is undoubtedly a very big deal indeed.
In short, China will still face an extra 30% tariffs (the 20% levies cast as punishment for China’s involvement in fentanyl imports and the 10% “floor” set on “Liberation Day”) on top of the residual 10% average from the Biden era.
But the rest of the extra tariffs will be paused for 90 days. China, in turn, has suspended its own retaliatory tariffs on the US.
The market has responded as you would probably have expected, with share prices leaping in relief. But that raises a question: is the trade war now over? Now that the two sides have blinked, can globalisation continue more or less as it had before?
That, it turns out, is a trickier and more complex question than it might first seem.

For one thing, even if one were to assume this is a permanent truce rather than a suspended one, it still leaves tariffs considerably higher than they were only last year. And China faces tariffs far higher than most other countries (tot up the existing ones and the Trump era ones and China faces average tariffs of around 40%, while the average for most countries is between 8% and 14%, according to Capital Economics).
In other words, the US is still implementing an economic policy designed to increase the cost of doing business with China, even if it no longer attempts to prevent it altogether. The fact that last week’s trade agreement with the UK contains clauses seemingly designed to encourage it to raise trade barriers against China for reasons of “security” only reinforces this suspicion. The trade war is still simmering, even if it’s no longer as hot as it was a few days ago.
And more broadly, the deeper impact of the trade rollercoaster in recent months is unlikely to disappear altogether. Companies remain more nervous about investing in factories and expansions in the face of such deep economic instability. No-one is entirely sure the White House won’t just U-turn once again.
That being said, it’s hard not to escape the conclusion that the US president has blinked in this trade war. In the face of a potential recession, he has pulled back from the scariest and most damaging of his tariffs, earlier and to a greater extent than many had expected.
That was in response to the opening gambit made on Saturday by Ukraine and its European allies.

Britain’s Sir Keir Starmer said they were “calling Putin out”, that if he was really serious about peace, he should agree to a 30-day unconditional ceasefire starting on Monday.
And they thought they had Donald Trump’s backing until he made his move.

Kremlin: ‘We don’t share Starmer’s view’
Late Sunday, he drove a cart and horses through claims of western unity, coming down on Putin’s side.
Ukraine, he said, should submit to the Russian leader’s suggestion of talks.
“Ukraine should agree to this – immediately”, he posted. Then: “I’m starting to doubt that Ukraine will make a deal with Putin…”
So much for the Coalition of the Willing having Putin where they wanted him.

Are Putin’s call for peace talks genuine?
Trump let him off the hook.
All eyes were then on President Zelenskyy, who has now in turn dramatically raised the stakes.
He will go to Istanbul, he said, and wait there for Vladimir Putin.
The fast-paced diplomacy aside, the last twenty-four hours have brought Europe closer to a moment of truth.
They thought they had Donald Trump’s support, and yet even with 30 nations demanding an unconditional ceasefire, the US president seemed, in the end, to side with the Russian leader.
He has helped Putin get out of a hole.
Yet again, Trump could not be counted on to pressure Vladimir Putin to end this war.
If America is no longer a reliable partner over Ukraine, Europe may need to go it alone, whatever the cost.
