The public service broadcaster committed a "significant breach" of industry standards by omitting to mention that the narrator of a documentary about the Gaza conflict was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An probe by Ofcom into Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, saying there had been "a serious error in relation to factual correctness".
Ofcom has directed the broadcaster to transmit a prime-time statement about its conclusions.
"Since this amounts to a significant violation of our code, we are directing the BBC to transmit a announcement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a timing to be determined," the regulator stated.
'Potential to Undermine Credibility'
The regulator's statement stated: "The inquiry we conducted found that the film's lack of disclosure that the voice's parent occupied a position in the Hamas-controlled authority was significantly deceptive.
"This implied that the viewers did not have essential details which may have been very significant to their judgment of the narrator and the information he presented.
"Trust is at the core of the relationship between a broadcaster and its viewers, notably for a public service broadcaster such as the public broadcaster.
"This error had the potential to undermine the exceptionally strong levels of trust that viewers would have invested 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 presenter's personal associations came to light, and in July an broadcaster's internal assessment found it violated the corporation's content policies on accuracy.
A corporation official commented: "The Ofcom ruling is in accordance with the conclusions of Peter Johnston's review, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on truthfulness, which aligns with clause 2.2 of the regulator's media standards.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will adhere to the directive as soon as the timing and language are confirmed."
