The BBC committed a "significant breach" of broadcasting rules by failing to disclose that the voice of a programme about the Gaza conflict was the son of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has instructed the broadcaster to broadcast a evening declaration about its findings.
"As this represents a significant violation of our code, we are directing the broadcaster to broadcast a announcement of our conclusions against it on BBC2 at 9pm, with a timing to be determined," the statement read.
'Possibility to Erode Credibility'
The watchdog's announcement said: "Our probe determined that the documentary's failure to disclose that the voice's father held a role in the Hamas-administered administration was substantially inaccurate.
"Consequently that the audience did not have vital facts which may have been highly relevant to their evaluation of the narrator and the details he provided.
"Trust is at the heart of the bond between a broadcaster and its viewers, notably for a state-funded media outlet such as the public broadcaster.
"This error had the possibility to erode the exceptionally strong degrees of trust that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The documentary was pulled from the BBC's streaming service in the month of February after the presenter's familial connections were revealed, and in this past July an broadcaster's internal assessment determined it violated the organization's content policies on truthfulness.
A corporation official commented: "The regulator's decision is in line with the conclusions of the corporation's inquiry, that there was a significant failing in the programme in relation to the corporation's content standards on accuracy, which aligns with clause 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the regulator's ruling in full. We will adhere to the sanction as soon as the timing and language are finalised."
