The British broadcaster engaged in a "significant breach" of industry standards by omitting to mention that the narrator of a documentary about Gaza was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a major oversight in relation to truthfulness".
Ofcom has instructed the broadcaster to air a peak-time declaration about its conclusions.
"Given this constitutes a serious breach of our regulations, we are instructing the BBC to transmit a statement of our findings against it on BBC2 at nine o'clock in the evening, with a date to be finalised," the statement read.
'Risk to Undermine Credibility'
The authority's statement said: "Our investigation determined that the documentary's failure to disclose that the narrator's father occupied a role in the Hamas-administered authority was substantially inaccurate.
"Consequently that the audience did not have vital facts which may have been extremely pertinent to their judgment of the presenter and the information he presented.
"Confidence is at the center of the connection between a media organization and its viewers, particularly for a public service broadcaster such as the public broadcaster.
"This oversight had the risk to damage the significantly high levels of credibility that audiences would have put in a BBC factual programme about the conflict in Gaza."
The film was withdrawn from the BBC's streaming service in last February after the boy's family links emerged, and in the month of July an corporation's own inquiry concluded it breached the broadcaster's editorial guidelines on accuracy.
A corporation official commented: "The authority's determination is in line with the conclusions of Peter Johnston's review, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on factual correctness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in complete. We will adhere to the directive as soon as the schedule and language are finalised."
