ISRAELI soldiers fired more than 900 bullets at a convoy of clearly marked Palestinian emergency vehicles in Gaza before advancing to kill the surviving aid workers, some of whom were shot ‘execution-style’ at close range, last March, a new joint investigation has revealed.
The report released on Monday by independent research agency Forensic Architecture and audio investigation group Earshot offers the most detailed reconstruction to date of the massacre in Tal as-Sultan, a neighbourhood west of Rafah in the southern Gaza Strip, on March 23, 2025.
Fifteen aid workers were killed in the attack, including paramedics from the Palestine Red Crescent Society (PRCS), firefighters from the Palestinian Civil Defence (PCD) and a staff member of the United Nations agency for Palestinian refugees (UNRWA).
The slain aid workers were then buried along with their vehicles.
The Israeli military initially claimed the vehicles were ‘uncoordinated’ and later admitted a ‘professional error’.
But the forensic analysis paints a different picture: a coordinated ambush, an absence of return fire and a calculated move to eliminate survivors.
The investigation relies heavily on a ‘situated testimony technique’ and advanced audio ballistics to analyse the sound of gunfire to determine the shooter’s distance, weapon type and direction.
Investigators analysed footage recovered from the phone of slain paramedic Rifaat Radwan, a PRCS paramedic who began recording at 5:09am, when the ambush began.
In a video lasting five and a half minutes, at least 844 gunshots were recorded. Combined with other recordings, the total documented count reached at least 910 gunshots.
In the video, filmed from inside one of the last two ambulances, Radwan can be heard asking his mother for forgiveness and reciting the Islamic declaration of faith, the shahada, before he dies.
According to Earshot’s analysis, 93 per cent of these shots featured a specific acoustic signature: a ‘supersonic shockwave’, followed by a muzzle blast.
This combination confirms that the camera – and the aid workers huddled around it – were directly in the line of fire.
‘The density of gunfire … frequently exceeds 900 rounds per minute,’ the report states, noting that, at one point, five shots were fired in just 67 milliseconds.
This rate of fire confirms that at least five shooters, likely many more, were firing simultaneously from an elevated sandbank approximately 40 metres away.
‘Israeli soldiers ambushed and subjected Palestinian aid workers to continuous assault by gunfire for over two hours’, between 5:09am and 7:13am, the report says.
The report challenges the Israeli narrative of a chaotic ‘combat zone’.
Instead, it describes a methodical massacre of Palestinian aid workers on their way to help people injured in Israeli strikes.
‘There was no exchange of fire in the area, and no tangible threat to the safety of those soldiers. These attacks did not happen in “a hostile and dangerous combat zone”, as was claimed by Israeli spokespersons,’ the report says.
By analysing the time delay between the sound of the gunshots and their echoes bouncing off a nearby concrete wall, investigators tracked the movement of the soldiers.
For the first four minutes, the soldiers held a fixed position on a sandbank. Then, the audio data shows the echo interval increasing, indicating the soldiers were moving down the hill, advancing roughly 50 metres towards the convoy while continuing to fire.
This corroborates the testimony of survivor Assaad al-Nassasra, a PRCS worker, who told investigators: ‘They were walking between (the aid workers) and shooting.’
The most chilling findings concern the final moments of the attack. Analysis of a subsequent phone call made by paramedic Ashraf Abu Libda to dispatchers captures the soldiers arriving at the vehicles.
The audio analysis identifies specific gunshots where the distinct ‘supersonic crack’ of the bullet disappears, leaving only the muzzle blast.
Ballistically, this indicates the shooter was within 1 to 4 metres (3 feet to 13 feet) of the victim.
These shots coincide with the final sounds of movement from Abu Libda, suggesting he was shot while lying on the ground.
A doctor who later examined the bodies confirmed the wounds were consistent with ‘execution-style’ killings.
The brutal killing of the 15 aid workers in March 2025 caused outrage, but Israel faced no legal or political consequences as it continued to receive backing from its Western allies, including the United States.
The report details a systematic attempt by Israeli forces to conceal the massacre in the hours that followed.
Satellite imagery from that morning revealed that bulldozers were deployed to the site.
The emergency vehicles were crushed and buried, and earth berms were constructed over the scene to block visibility.
These forensic findings align with satellite imagery.
In a report published on March 30, 2025, Sanad revealed imagery taken on March 25 showing that at least five rescue vehicles had been ‘completely destroyed’ and buried in sand by Israeli forces on al-Muharrarat Street – the site of the massacre.
At the time, the Palestinian Civil Defence condemned the act as a ‘crime of extermination’, stating that Israeli forces deliberately ‘altered the landmarks of the place’ and used heavy machinery to hide the bodies of the victims.
‘Israeli military personnel acted intentionally to conceal and disrupt evidence … by burying the bodies of the victims (and) burying the mobile phones,’ the Forensic Architecture report says.
Survivor al-Nassasra was detained, taken to Israel’s notorious Sde Teiman detention camp, and tortured for 37 days.
He testified that soldiers confiscated and buried his phone, likely to hide evidence.
One of the two PRCS survivors of the attack was later used as a ‘human tool’ at an Israeli military checkpoint near the incident site, the report says.
In a rare instance of identification, the audio analysis was able to isolate and enhance the voices of the Israeli soldiers speaking Hebrew during the attack.
The investigation identifies three soldiers by name – Elias (referred to as Lalas), Yotam, and Amatzia – based on their conversations as they moved among the bodies.
In one recording, a soldier is heard asking, ‘Lalas, did you finish?’ before receiving an order to ‘put the guns on them’.
The report concludes that there was ‘no exchange of fire in the area, and no tangible threat to the safety of those soldiers’, debunking Israeli claims of a battle. Instead, it documents a deliberate attack on a humanitarian convoy that ended in the calculated execution of those who survived the initial barrage.
Describing it as ‘one of the darkest moments’ of the war by the Palestine Red Crescent Society (PRCS), this massacre killed eight of its aid workers, another six from Palestinian Civil Defence, and a UN relief agency staffer.
Triggering international condemnation, the report reconstructs, minute by minute, how the massacre unfolded.
Using video and audio recordings from the incident, open-source images and videos, satellite imagery, social media posts, and other materials, as well as in-depth interviews with two survivors of the attack, the groups were able to digitally reconstruct the scene and events surrounding the massacre.
According to the findings of the report, at least 93% of the gunshots recorded in the first minutes of the attack were fired directly towards the emergency vehicles and aid workers by Israeli soldiers. During this time, at least five shooters fired simultaneously.
Witness testimonies suggest as many as 30 soldiers were present in the area.
The body of Anwar al-Attar was found near the ambush site on March 27, and the bodies of the other 14 aid workers, all wearing identifying uniforms or volunteer vests of their respective organisations, were found in a mass grave near the site on March 30.
The area surrounding the incident site was further transformed by the Israeli military’s construction of the ‘Morag Corridor’ security zone and the erection of an aid distribution site operated by the Gaza Humanitarian Foundation, where, not long after, people were again killed trying to access food.
