FBI probes killing of Palestinian-American reporter Abu Akleh; Israel: Grave mistakeMove represents about-face by US, which had said it wouldn’t open its own probe into death of reporter who Israel says was likely shot by IDF in error; Gantz: We won’t cooperateJacob Magid is The Times of Israel's US correspondent based in New YorkThe US Federal Bureau of Investigation is launching an investigation into the killing of Palestinian-American journalist Shireen Abu Akleh, apparently by an Israeli soldier, officials said Monday, with Israel immediately rejecting cooperation with the probe.The 51-year-old Abu Akleh, who was wearing a vest marked “Press” and a helmet, was shot dead on May 11 during clashes between Israeli troops and Palestinian gunmen that broke out after soldiers raided the Jenin refugee camp, in the northern West Bank, amid a wider terror crackdown.Defense Minister Benny Gantz tweeted that the decision to probe Abu Akleh’s “unfortunate” death was “a grave mistake.” He noted that the IDF had conducted its own investigation into the Al Jazeera reporter’s death and that those findings were shared with the Biden administration.The US seemed to back off later that week, with State Department spokesman Ned Price saying it was not on Washington or “or any other country or entity to say precisely what the IDF or any military or security organization around the world should do.”Israel’s Foreign Ministry declined a request to comment on Monday, as did the US Justice Department, though neither denied the opening of an investigation.However, such separate investigations are not the rule and it is rare, if not unprecedented, for them to occur in a US-allied country like Israel that is recognized in Washington as having a credible and independent judicial system."
