The British broadcaster engaged in a "significant breach" of industry standards by omitting to mention that the voice of a documentary about the Gaza situation was the offspring of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "materially misleading".
The chief executive of the broadcaster had already issued an apology, saying there had been "a significant failing in relation to truthfulness".
The regulator has directed the broadcaster to transmit a evening announcement about its conclusions.
"Given this constitutes a major infringement of our rules, we are directing the corporation to transmit a message of our determinations against it on BBC Two at 21:00, with a schedule to be confirmed," the regulator stated.
'Possibility to Undermine Confidence'
The authority's announcement said: "The inquiry we conducted determined that the programme's lack of disclosure that the narrator's male guardian occupied a post in the Hamas-run authority was substantially inaccurate.
"It meant that the audience did not have critical information which may have been extremely pertinent to their judgment of the presenter and the content he shared.
"Credibility is at the heart of the connection between a media organization and its viewers, notably for a state-funded media outlet such as the BBC.
"This oversight had the risk to damage the very considerable amounts of credibility that audiences would have put in a BBC factual programme about the Gaza conflict."
The programme was pulled from the online platform in the month of February after the narrator's familial connections emerged, and in this past July an corporation's own inquiry determined it violated the corporation's journalistic standards on truthfulness.
A corporation official said: "The authority's determination is in agreement with the results of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on factual correctness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we accept the authority's determination in full. We will comply with the sanction as soon as the timing and language are confirmed."
