The British broadcaster committed a "significant breach" of media regulations by omitting to mention that the narrator of a film about the Gaza situation was the offspring of a Hamas representative, as ruled by regulatory body Ofcom.
An inquiry by Ofcom into Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The head of the BBC had previously apologised, noting there had been "a significant failing in relation to truthfulness".
The regulator has instructed the corporation to air a peak-time statement about its findings.
"As this represents a serious breach of our rules, we are instructing the BBC to broadcast a statement of our determinations against it on BBC2 at nine o'clock in the evening, with a schedule to be confirmed," the regulator stated.
'Potential to Undermine Credibility'
The regulator's announcement declared: "Our investigation determined that the documentary's failure to disclose that the voice's father served in a post in the Hamas-run authority was significantly deceptive.
"It meant that the viewers did not have critical information which may have been highly relevant to their assessment of the narrator and the details he presented.
"Credibility is at the center of the bond between a media organization and its audience, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to undermine the exceptionally strong amounts of credibility that audiences would have placed in a documentary produced by the BBC about the Gaza conflict."
The film was pulled from the BBC's streaming service in the month of February after the narrator's personal associations emerged, and in July an corporation's own inquiry found it violated the organization's journalistic standards on accuracy.
A representative for the broadcaster stated: "The authority's determination is in agreement with the findings of Peter Johnston's review, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with the regulator's ruling in its entirety. We will adhere to the directive as soon as the date and language are determined."
