Israel has asked the UK for more information on the death of British cameraman James Miller, who was shot in Gaza in May 2003.
Israel says it is unclear who shot James Miller
Attorney general Menachem Mazuz has asked to see footage of the incident, which was filmed by a local TV crew.
It comes as a deadline set by the UK government for Israel to open a criminal investigation expired.
An Israeli inquiry cleared a soldier of firearms misuse but a UK inquest later ruled Mr Miller was unlawfully killed.
Mr Miller, from Devon, was filming a documentary when he was shot dead in the town of Rafah. His family says there is clear evidence the 34-year-old was killed by an Israeli soldier.
The film has already been analysed by an acoustic expert working for the Metropolitan Police. He concluded that the shots fired that night came from only one direction - from where an Israeli armoured personnel carrier was located.
In the footage, Mr Miller is seen waving a white flag as he steps from a building in Gaza. There is a shot. His colleague shouts, "We're British journalists."
There is then a second shot, which hits Mr Miller in the neck.
British officials have told the BBC they aim to deliver the original film within a week, and that they expect to hear from the Israeli authorities again within a further four to five weeks.
At the end of June, the UK attorney general at the time, Lord Goldsmith, gave the Israeli authorities until 7 August to open a criminal investigation.
But British officials and Mr Miller's family say they are willing to be flexible on the timetable, as long as the Israeli attorney general takes the new evidence into account.
