The paramedics and rescue workers killed in an Israeli shooting in the Gaza Strip last month died mainly from gunshots to the head or chest, while others had shrapnel injuries or other wounds, according to autopsy reports obtained by the New York Times.

Israeli troops had fired on ambulances and a fire truck sent by the Palestine Red Crescent Society and the Civil Defense, according to witness accounts, video and audio of the March 23 attack.

Israel acknowledged carrying out the attack, which killed 15 men: 14 rescue workers and a United Nations employee who drove by after the others were shot. Israeli soldiers buried most of the bodies in a mass grave; crushed the ambulances, fire truck and a U.N. vehicle; then buried those as well.

The Israeli military has offered shifting explanations for why its troops fired on the emergency vehicles and said, without providing evidence, that some of the dead men had been Hamas operatives. Israel’s military said it was investigating the killing.

The episode drew international condemnation, and experts described it as a war crime.

The autopsies were carried out between April 1 and April 5, according to the reports, after a team of aid workers recovered the men’s bodies from southern Gaza. The Times reviewed autopsy results for all the men except the U.N. employee. They were performed by Dr. Ahmad Dhair, the head of the Gaza Health Ministry’s forensic medicine unit.

Dr. Arne Stray-Pedersen, a forensic pathologist at Oslo University Hospital in Norway, who had been in Gaza earlier in March to train doctors in forensic medicine, reviewed photos of the autopsies and consulted with Dhair to write a summary report.

The 14 men were wearing either their Red Crescent or Civil Defense uniforms, in part or in whole, at the time of death, the autopsy reports said. Video of part of the attack shows that when Israeli troops began shooting at them, a few of the paramedics had exited their vehicles and were clearly visible in their uniforms, with reflective bands across the back, arms and legs that shone brightly in the lights of the ambulances.

The autopsy reports said 11 of the men had gunshot wounds, including at least six who were shot in their chests or backs and four who were shot in the head. Most had been shot multiple times.

One man had several shrapnel wounds in his chest and abdomen; two others had injuries that the autopsy reports said were “consistent” with shrapnel, possibly related to an explosion. While sustained gunfire can be heard on the video and in audio recordings of part of the attack, it is unclear whether there was an additional blast that might have caused such injuries.

Several of the bodies were missing limbs or other body parts, the reports said. One man’s body was severed from the pelvis down, his autopsy report said.

The bodies were all partly or severely decomposed, according to the autopsy reports and photos. That made it challenging to draw additional conclusions, including whether the men had been shot at close range or from farther away, Stray-Pedersen said in an interview.

After examining the first few bodies in late March, Dhair had told the Times and other news outlets that one victim had marks and bruises on his wrists, suggesting that his hands had been tied. Dhair cautioned that further investigation was needed to determine whether that was the case.

Another medic dies in Israeli airstrike

Meanwhile, an Israeli airstrike hit the northern gate of a field hospital in the Gaza Strip on Tuesday, killing a medic and wounding nine other people, a hospital spokesman said.

The strike hit the Kuwaiti Field Hospital in the Muwasi area, where hundreds of thousands have sought shelter in sprawling tent camps. The wounded were all patients and medics, and two of the patients were in critical condition after the strike, said Saber Mohammed, a hospital spokesman.

There was no immediate comment from the Israeli military.

Netanyahu visits Gaza

In the call with French President Emmanuel Macron, Israeli Prime Minister Benjamin Netanyahu said the creation of a Palestinian state would be “a huge reward for terrorism” and result in a militant-run entity just miles from Israeli cities.

In his own statement posted on X, Macron called for another ceasefire, the release of hostages and renewing the delivery of humanitarian aid to Gaza, which Israel has blocked for over a month. He did not mention recognition of a Palestinian state.

Macron said last week that France should aim to recognize a Palestinian state by June when it joins Saudi Arabia in hosting an international conference on implementing a two-state solution.

Later on Tuesday, Netanyahu’s office said that he visited northern Gaza. He has previously entered Gaza a handful of times during the Hamas war.
