The public service broadcaster committed a "significant breach" of media regulations by failing to disclose that the voice of a programme about the Gaza conflict was the offspring of a Hamas representative, as ruled by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a significant failing in relation to accuracy".
The regulator has directed the corporation to transmit a peak-time declaration about its conclusions.
"Given this constitutes a major infringement of our regulations, we are directing the broadcaster to transmit a statement of our findings against it on BBC2 at 9pm, with a schedule to be determined," the regulator stated.
'Risk to Damage Confidence'
The authority's report said: "Our investigation determined that the film's lack of disclosure that the voice's male guardian served in a role in the Hamas-controlled government was materially misleading.
"It meant that the public did not have essential details which may have been extremely pertinent to their evaluation of the presenter and the information he provided.
"Credibility is at the heart of the relationship between a media organization and its viewers, particularly for a public service broadcaster such as the BBC.
"This error had the possibility to erode the significantly high degrees of credibility that audiences would have placed in a factual film from the broadcaster about the Gaza conflict."
The film was withdrawn from iPlayer in the month of February after the presenter's familial connections came to light, and in the month of July an corporation's own inquiry concluded it breached the corporation's editorial guidelines on accuracy.
A BBC spokesperson said: "The Ofcom ruling is in accordance 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 corresponds to regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in complete. We will adhere to the directive as soon as the date and wording are finalised."
