RAMALLAH, West Bank (AP) — The Israeli military said Tuesday an American activist killed in the West Bank last week was likely shot “indirectly and unintentionally” by its soldiers, drawing a strong rebuke from U.S. Secretary of State Antony Blinken and the activist’s family.

Israel said a criminal investigation has been launched into the killing of Aysenur Ezgi Eygi, a 26-year-old activist from Seattle who was taking part in a demonstration against settlements. Doctors who treated Eygi, who also held Turkish citizenship, said she was shot in the head.

Blinken condemned the “unprovoked and unjustified” killing when asked about the Israeli inquiry at a news conference in London. “No one should be shot while attending a protest,” he said. “The Israeli security forces need to make some fundamental changes in the way they operate in the West Bank.”

Eygi’s family in the U.S. released a statement saying “we are deeply offended by the suggestion that her killing by a trained sniper was in any way unintentional. The disregard shown for human life in the inquiry is appalling.”

During Friday’s demonstration, clashes broke out between Palestinians throwing stones and Israeli troops firing tear gas and ammunition, according to Jonathan Pollak, an Israeli protester who witnessed the shooting of Eygi.

Pollak said the violence had subsided about a half hour before Eygi was shot, after protesters and activists had withdrawn several hundred meters (yards) away from the site of the demonstration. Pollak said he saw two Israeli soldiers mount the roof of a nearby home, train a gun in the group’s direction and fire, with one bullet hitting Eygi.

Israel said its inquiry into Eygi’s killing “found that it is highly likely that she was hit indirectly and unintentionally by (Israeli army) fire which was not aimed at her, but aimed at the key instigator of the riot.” It expressed its “deepest regret” at her death.

International Solidarity Movement, the activist group Egyi was volunteering with, said it “entirely rejects” the Israeli statement and that the “shot was aimed directly at her.”

The killing came amid a surge of violence in the West Bank since the Israel-Hamas war began in October, with increasing Israeli raids, attacks by Palestinian militants on Israelis, attacks by Israeli settlers on Palestinians and heavier military crackdowns on Palestinian protests.

Israel says it thoroughly investigates allegations of its forces killing civilians and holds them accountable. It says soldiers often have to make split-second decisions while operating in areas where militants hide among civilians. But human rights groups say soldiers are very rarely prosecuted, and even in the most shocking cases — and those captured on video — they often get relatively light sentences.

The Palestinian Authority held a funeral procession for Eygi in the West Bank city of Nablus on Monday. Turkish authorities said they are working on repatriating her body to Turkey for burial in the Aegean coastal town of Didim, as per her family’s wishes.

Eygi’s uncle said in an interview with the Turkish TV channel HaberTurk that she kept her visit to the West Bank secret from at least some of her family members. She said she was traveling to Jordan to help Palestinians there, he said.

“She hid the fact that she was going to Palestine. She blocked us from her social media posts so that we would not see them,” Yilmaz Eygi said.

The deaths of American citizens in the West Bank have drawn international attention, such as the fatal shooting of a prominent Palestinian-American journalist, Shireen Abu Akleh, in 2022 in the Jenin refugee camp.

Several independent investigations and reporting by The Associated Press determined that Abu Akleh was likely killed by Israeli fire. Months later, the military said there was a “high probability” one of its soldiers had mistakenly killed her but that no one would be punished.

In January 2022, Omar Assad, a 78-year-old Palestinian-American, died of a heart attack after Israeli troops at a checkpoint dragged him from his car and made him lie facedown, bound, temporarily gagged and blindfolded. The military ruled out criminal charges and said it was reprimanding one commander and removing two others from leadership roles for two years.

The U.S. had planned to sanction a military unit linked to abuses of Palestinians in the West Bank but ended up dropping the plan.

The deaths of Palestinians who do not have dual nationality rarely receive the same scrutiny.

Human rights groups say Israel military investigations into Palestinians’ deaths reflect a pattern of impunity. B’Tselem, a leading Israeli watchdog, became so frustrated that in 2016 it halted its decades-long practice of assisting investigations and called them a “whitewash.”

Last year, an Israeli court acquitted a member of the paramilitary Border Police charged with reckless manslaughter in the deadly shooting of 32-year-old Eyad Hallaq, an autistic Palestinian man in Jerusalem’s Old City in 2020. The case had drawn comparisons to the police killing of George Floyd in the United States.

In 2017, Israeli soldier Elor Azaria was convicted for manslaughter and served nine months after he killed a wounded, incapacitated Palestinian attacker in the West Bank city of Hebron. The combat medic was caught on video fatally shooting Abdel Fattah al-Sharif, who was lying motionless on the ground.

That case deeply divided Israelis, with the military saying Azaria had clearly violated its code of ethics, while many Israelis — particularly on the nationalist right — defended his actions and accused military brass of second-guessing a soldier operating in dangerous conditions.
