Almost two weeks after the death of the veteran Palestinian-American reporter for Al Jazeera, a reconstruction by The Associated Press lends support to assertions from both Palestinian authorities and Abu Akleh’s colleagues that the bullet that cut her down came from an Israeli gun.

Any conclusive answer is likely to prove elusive because of the severe distrust between the two sides, each of which is in sole possession of potentially crucial evidence.

Multiple videos and photos taken on the morning of May 11 show an Israeli convoy parked just up a narrow road from Abu Akleh, with a clear line of sight. They show the reporters and other bystanders in real time taking cover from bullets fired from the direction of the convoy.

The only confirmed presence of Palestinian freedom fighters was on the other side of the convoy, some 300 metres away, mostly separated from Abu Akleh by buildings and walls. Israel says at least one freedom fighter was between the convoy and the journalists, but it has not provided any evidence or indicated the shooter’s location. Palestinian witnesses say there were no freedom fighters in the area and no gunfire until the barrage that struck Abu Akleh and wounded another reporter.

Those witnesses say they have no doubt that it was Israeli soldiers who killed Abu Akleh, now celebrated as a martyr to both journalism and the Palestinian cause. The Israeli military says she was killed in a complex shootout between soldiers and freedom fighters, and that only a full investigation — including forensic analysis of the bullet — could prove who fired the fatal shot.

The Palestinians have refused to hand over the bullet or cooperate with Israel in any way on the investigation, but say they will share the results of their own probe with any other party.

Abu Akleh’s death has further heightened Mideast tensions amid a wave of violence and raised new concerns over the safety of reporters covering Israel’s nearly 55-year military occupation of the West Bank, which the Palestinians want as the main part of their future state.

AP reporters visited the location where Abu Akleh was killed on the edge of the Jenin refugee camp in the northern West Bank, as well as the scene of a nearby battle with Israeli forces captured on a video shared by Israel.

Interviews with five Palestinian eyewitnesses corroborate an analysis by the Dutch-based Bellingcat research group indicating Israeli forces were closer to Abu Akleh and had a better line of sight. The group, which specialises in geolocating events in war zones by analysing photos and videos shared online, pinpointed the location of the convoy just up a narrow road from where Abu Akleh was killed.

The road and the convoy

Reporters who were with Abu Akleh say that when they arrived at the scene it was quiet, with no clashes or freedom fighters in the immediate area. Ali Samoudi, an Al Jazeera producer from Jenin, said he called people inside the camp to get an idea of what was happening.

Then they proceeded to a long, narrow road sloping up from an open area to a cluster of concrete buildings where an Israeli army convoy was parked some 200m away. Each reporter was wearing a helmet and a blue vest labeled “PRESS” in large lettering.

“We stepped out into the open so they could see us,” Samoudi told the AP. “They didn’t indicate that we should leave, so we went slowly, walking forward about 20m.”

Shatha Hanaysheh, a local photographer, said they remained there for five to 10 minutes, talking and even laughing in full view of the soldiers. A video that appears to capture the first shots supports her account.

Samoudi said the soldiers fired a warning shot, causing him to duck and run backwards. The second shot hit him in the back. Abu Akleh was shot in the head and appears to have died instantly, Hanaysheh sheltered on the other side of a tree next to a wall. Tree bark on the side facing the army appears to have been chipped away by gunfire or shrapnel.

“We saw that the gunfire came from the army,” Hanaysheh said. “When Ali and Shireen and I ran for cover, we ran away from them.”

Sharif Azer, a local resident who was on his way to work, heard the gunfire and ran over to help. He can be seen in another widely shared video climbing over the wall where Hanaysheh was taking cover and helping her to escape.

Several gunshots can be heard after Abu Akleh was killed, as people take cover on either side of the road. When Azer moves away from the tree, shots ring out and he backs up, indicating they are coming from the army’s position. He says he could see the soldiers pointing their guns.

“They fired on us more than once. Every time someone approached, they fired at them,” he said.

A possible scenario

The Israeli military’s initial inquiry into the shooting said there were two possibilities.

In the first, it said Palestinian freedom fighters on the other side of the convoy, to the south, were recklessly firing hundreds of rounds, one of which could have struck Abu Akleh, who was some 300m away. Bullets fired from an M16 can travel well over 1,000m.

But the military hasn’t provided any visual evidence, aside from footage of Palestinian freedom fighters firing from another location that did not have a line of sight toward Abu Akleh.

The AP did not uncover any evidence to support this first scenario.

The second scenario, at this point, appears more plausible.

Lt Col Amnon Shefler, an army spokesman, says there was at least one Palestinian gunman on the road between the troops and the journalists, “in the vicinity” of Abu Akleh. That freedom fighter allegedly fired multiple times at one of the army vehicles, and a soldier inside it returned fire with a rifle equipped with a telescopic scope.

The army’s probe has zeroed in on that rifle, Shefler said, though it still believes a stray Palestinian bullet could have killed her.

The army says it cannot provide an answer without comparing the bullet to the weapon. “Without the possibility of examining the bullet, the doubt remains,” Maj Gen Yifat Tomer-Yerushalmi, the army’s chief prosecutor, said in a speech on Monday.

She said that because the killing occurred in an active combat zone, there would be no decision on whether to open a criminal investigation until the initial probe is complete.

Videos posted on social media that day contain sounds of heavy gunfire in other parts of Jenin, including near a house surrounded by Israeli military vehicles conducting an arrest raid about 1.5 kilometres away from where Abu Akleh was shot.

All of the witnesses who spoke to the AP insisted there were no freedom fighters in the area between the reporters and the army. The area is mostly open, but a gunman could have potentially sheltered unseen in the brush-filled cemetery on the road’s eastern side or an open-air brick factory next to where the journalists were located.

No freedom fighters can be seen in any of the videos showing the journalists’ location. The Palestinian Health Ministry says there were no other Palestinians killed or wounded that day in Jenin. Local media also have no record of any other Palestinian casualties.

Walid Omary, who oversees Al Jazeera’s coverage of the Palestinian territories, said he had seen no evidence of any freedom fighters between the reporters and the army.

“If there was a Palestinian freedom fighters there, why not shoot the freedom fighters? They have snipers,” he said. “It’s clear to us now that they targeted Shireen.”

Separate investigations

Almost immediately after the shooting, Israel called for a joint investigation with the Palestinian Authority (PA), which administers parts of the occupied West Bank, and asked it to hand over the bullet that killed Abu Akleh for ballistic analysis. Israel invited Palestinian and American representatives to participate in the investigation.

The PA refused, saying Israel cannot be trusted to investigate itself. Within hours of the shooting, both the PA and Al Jazeera accused Israel of deliberately targeting Abu Akleh, but provided no specific evidence for the claim, which Israel strongly denies.

A spokesman for President Mahmoud Abbas said the Palestinians are conducting a “pure, professional investigation” and will share the results with international bodies. He declined to provide details of the probe or address questions about trying to match the bullet to the weapon.

“We are sure that Israel is responsible for the killing, and we have evidence, proof, and witnesses confirming that,” Nabil Abu Rdeneh told the AP. ”We have no confidence in Israeli investigations because their goal is to falsify the facts.”

Israeli investigations into shootings of Palestinians often drag on for months or years before being quietly shelved, and rights groups say soldiers are rarely held accountable.

Israeli authorities initially suggested the Palestinian fighters in the video they shared might have killed Abu Akleh. They backtracked after B’Tselem, an Israeli rights group, circulated another video showing it was virtually impossible for them to have shot her, since the two locations were hundreds of metres apart and separated by buildings and walls. B’Tselem is still conducting its own investigation.

Palestinian investigators are in possession of the bullet that killed Abu Akleh, which was recovered from her head. Samoudi says the bullet that struck him shattered, leaving some fragments inside his back. It’s unclear if any other fragments have been recovered.

Lior Nadivi, a former crime scene investigator and firearms examiner for the Israeli police, said the bullet that killed Abu Akleh would potentially contain a trove of evidence.

A deformation might indicate it ricocheted. Markings would show the type of weapon, and a microscopic signature could potentially be used to match the bullet to a specific firearm. He said there was “no way” to tamper with a bullet without leaving obvious marks on it.

But Nadivi said it was also important to have a full picture of what happened.

“You need to position all the people who fired in the general direction of this journalist and then try to analyse what happened to each bullet,” he said. “There is a lot of information that you need, and right now we’ve got nothing.”

In the end, it could prove impossible to know exactly what happened; neither side is likely to accept conclusions reached by the other. The United States, Israel’s closest ally, says it is “working to bridge cooperation between the parties,” but there’s no indication of any progress.

Last week, 57 House Democrats called for an FBI investigation. Both Israel and the PA would have to request US assistance, and neither appears to have done so. Israel has invited the US to participate in an observer role.

In theory, each side could submit evidence to a third party for analysis. But neither side has expressed interest in that kind of investigation, and each could accuse the other of tampering with evidence if it didn’t like the result.

Samoudi visited the scene of the killing in a wheelchair on Thursday, as supporters set up a makeshift memorial. Hanaysheh came as well, but kept her distance from the tree where she was nearly killed, saying she was still too traumatised to approach it.

She hasn’t given up the work though.

Two days after Abu Akleh was killed, Israeli forces returned to Jenin to carry out another raid. Israel says it is targeting freedom fighters after a series of attacks in recent weeks, many carried out by assailants from in and around Jenin.

Hanaysheh said even more journalists than usual came out to cover it — and that she was among them.

“Any journalist anywhere knows that they can be killed, but if we don’t do this work then no one else will,” she said. “We know the occupation doesn’t want what happens here to get out.”
