The family of a Palestinian-American reporter killed while covering an Israeli raid in the occupied West Bank lashed out at US President Joe Biden in a letter released Friday (local time) over his administration's response to her death.

Relatives of Al Jazeera reporter Shireen Abu Akleh expressed "grief, outrage and (a) sense of betrayal," accusing the US of trying to erase Israel's responsibility for her death. A US statement earlier this week said Israeli fire likely killed her but that the May 11 shooting in the West Bank town of Jenin was not intentional.

Fallout from the killing is likely to cast a shadow over Biden's trip to Israel and the occupied West Bank next week. The family asked Biden to meet with them when he visits the region. The White House declined to comment on the letter or the request for a meeting.

A reconstruction by The Associated Press lent support to Palestinian eyewitnesses who said she was shot by Israeli forces without making a final determination. Investigations by CNN, the New York Times and the Washington Post, as well as monitoring by the UN human rights office, reached similar conclusions.

Israel denies she was deliberately targeted, and says she could have been shot by an Israeli soldier or a Palestinian militant during an exchange of fire. The US State Department said in a July 4 statement that the bullet that killed her was too badly damaged to determine who fired it.

The statement said the US had summarised separate investigations by Israel and the Palestinian Authority, concluding that she was likely struck by Israeli fire. But it found "no reason to believe that this was intentional," saying it was the result of "tragic circumstances". The US did not explain how it reached those conclusions or cite evidence to support them.

The Abu Akleh family said "all available evidence" suggests she was deliberately killed by an Israeli soldier and that the administration had "thoroughly failed to meet the bare minimum expectation" of a credible, independent investigation.

"Instead, the United States has been skulking toward the erasure of any wrongdoing by Israeli forces," they said. "It is as if you expect the world and us to now just move on. Silence would have been better."

Asked about the letter, White House press secretary Karine Jean-Pierre said she had not yet seen it and declined to comment on Biden's travel plans. She said Biden has been closely monitoring the investigation and that senior US officials are in touch with the family.

"We feel their pain. We can't even imagine what they must be going through," she said. "We continue to urge cooperation between Israel and the Palestinian Authority on next steps and we definitely continue to urge accountability."

US lawmakers have pressed the administration for an independent investigation into the killing of Abu Akleh, a veteran on-air correspondent for Al Jazeera's Arabic language service who was widely known and respected across the Arab world.

Abu Akleh, who was 51, had spent a quarter-century reporting on the harsh realities of life under Israeli military rule. Palestinians view her as a martyr to journalism as well as their national cause.

Israeli police drew widespread criticism when they beat mourners and pallbearers at her funeral in Jerusalem on May 14. An Israeli newspaper last month reported that a police investigation found wrongdoing by some of its officers, but said those who supervised the event will not be seriously punished.
