The public service broadcaster engaged in a "serious breach" of broadcasting rules by omitting to mention that the voice of a film about the Gaza conflict was the child of a Hamas representative, as ruled by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, saying there had been "a significant failing in relation to factual correctness".
The authority has instructed the broadcaster to transmit a evening announcement about its decisions.
"Given this constitutes a major infringement of our regulations, we are instructing the BBC to air a statement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a timing to be confirmed," it said.
'Possibility to Undermine Credibility'
The regulator's announcement declared: "Our probe determined that the programme's lack of disclosure that the narrator's father served in a position in the Hamas-run authority was substantially inaccurate.
"This implied that the audience did not have critical information which may have been highly relevant to their judgment of the narrator and the information he shared.
"Credibility is at the center of the connection between a media organization and its viewers, notably for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the possibility to undermine the very considerable levels of credibility that audiences would have placed in a documentary produced by the BBC about the Gaza conflict."
The film was withdrawn from the online platform in the month of February after the presenter's familial connections emerged, and in July an broadcaster's internal assessment determined it breached the corporation's editorial guidelines on truthfulness.
A corporation official stated: "The regulator's decision is in line with the results of the internal assessment, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the regulator's ruling in full. We will adhere to the directive as soon as the schedule and wording are confirmed."
