The U.N. conclusions — which included the finding that “several single, seemingly well-aimed bullets” were fired at Abu Akleh and three other journalists from the direction of Israeli forces — mirrored the conclusions of several independent investigations, including a review by The Washington Post, which found that Israeli troops likely fired the fatal shot.

On Thursday, 24 U.S. senators sent a letter to President Biden urging that the United States be “directly involved in investigating” Abu Akleh’s death. The letter, citing a lack of progress toward the establishment of an independent investigation — and the fact that Abu Akleh was an American — said the U.S. government “has an obligation to ensure that a comprehensive, impartial, and open investigation into her shooting death is conducted.”

On the day Abu Akleh was killed, Israel Defense Forces spokesman spokesperson Ran Kochav first acknowledged the incident in a 7:45 a.m. tweet, saying: “The possibility that journalists were injured, possibly by Palestinian gunfire, is being investigated.”

Later that morning, he told Army Radio that it was “likely” that a Palestinian gunman was responsible. By the end of the day, Defense Minister Benny Gantz walked back those assertions and said an Israeli soldier could have also been responsible for firing the fatal shot.

A week after the killing, however, the army said that it had not found evidence of criminal conduct in the killing and so there would be no military police probe.

“More than six weeks after the killing of journalist Shireen Abu Akleh and injury of her colleague Ali al-Samoudi in Jenin on 11 May 2022, it is deeply disturbing that Israeli authorities have not conducted a criminal investigation,” the statement from the U.N. Human Rights Office said.

The Post’s examination — based on a review of five dozen videos, social media posts and photos of the event, two physical inspections of the area and two independent acoustic analyses — found that an Israeli soldier likely shot and killed Abu Akleh. The audio analyses of what was likely the fatal gunshots pointed to one person shooting from an estimated distance that nearly matched the span between the journalists and the IDF convoy.

The Post’s review found no evidence of activity of armed Palestinians in the immediate vicinity of the place where Abu Akleh, and a group of other journalists, were standing before the killing.

“Perpetrators must be held to account,” said the U.N. statement.
