JERUSALEM — Veteran Al Jazeera journalist Shireen Abu Akleh, one of the satellite channel’s best-known reporters, was shot and killed Wednesday while covering an Israeli military raid in the occupied West Bank. The broadcaster and two reporters who were with her blamed Israeli forces.

Israeli Defense Minister Benny Gantz promised an investigation and said he was in touch with U.S. and Palestinian officials. The Israeli military initially suggested that Abu Akleh might have been killed by stray fire from Palestinians, but Gantz was more cautious Wednesday.

“We are trying to figure out exactly what happened,” he said. “I don’t have final conclusions.”

He said Israel asked the Palestinian medical team that performed a preliminary autopsy to hand over the fatal bullet for further examination. The head of the Palestinian forensics institute, Rayan al-Ali, said earlier Wednesday that the bullet was deformed, and he could not determine who fired it.

Abu Akleh’s death could draw new scrutiny of Israel’s military justice system, which is being examined as part of a war crimes probe conducted by the International Criminal Court. It also threatened to further strain often rocky relations between the army and the international media.

Abu Akleh, 51, was a respected and familiar face in the Middle East, known for her coverage on Al Jazeera Arabic of the harsh realities of Israel’s open-ended military occupation of the Palestinians, now in its 55th year. She was widely recognized in the West Bank and was also a U.S. citizen.

Her death reverberated across the region. There was also an outpouring of grief in the West Bank.

In Ramallah, the seat of the Palestinian autonomy government, Abu Akleh’s body, draped in a Palestinian flag and covered by a wreath of flowers, was carried through downtown streets. Hundreds chanted, “with our spirit, with our blood, we will redeem you, Shireen.”

On Thursday, a procession was to take the body for burial in Jerusalem, where Abu Akleh was born.

Abu Akleh was killed by a shot to the head while on the outskirts of the Jenin refugee camp in the northern West Bank, known as a bastion of militants. Israel has conducted near-daily raids in Jenin in recent weeks following a series of deadly attacks inside Israel carried out by militants.

Gantz said Israeli forces came under attack by indiscriminate fire by Palestinian militants from several directions.

Gantz described the situation as chaotic.

“I am very sorry for what happened,” he told reporters.

Palestinian journalists who were with Abu Akleh at the time said they made their presence known to Israeli soldiers, and that they did not see militants in the area.

Abu Akleh’s producer, journalist Ali Samoudi, was hospitalized in stable condition after being shot in the back. He said any suggestion they were shot by militants was a “lie.”
