The public service broadcaster committed a "significant breach" of industry standards by omitting to mention that the narrator of a documentary about the Gaza situation was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, saying there had been "a major oversight in relation to accuracy".
Ofcom has directed the corporation to air a prime-time statement about its conclusions.
"As this represents a serious breach of our code, we are instructing the broadcaster to transmit a statement of our findings against it on BBC2 at nine o'clock in the evening, with a schedule to be finalised," the statement read.
'Possibility to Damage Confidence'
The regulator's report said: "Our probe concluded that the film's lack of disclosure that the voice's father held a role in the Hamas-administered government was significantly deceptive.
"Consequently that the public did not have critical information which may have been very significant to their assessment of the voice and the details he provided.
"Confidence is at the center of the connection between a television network and its viewers, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This error had the possibility to undermine the very considerable amounts of credibility that viewers would have placed in a BBC factual programme about the conflict in Gaza."
The film was pulled from the online platform in the month of February after the narrator's family links emerged, and in the month of July an internal BBC review determined it infringed the organization's journalistic standards on truthfulness.
A BBC spokesperson commented: "The authority's determination is in accordance with the findings of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with Ofcom's decision in full. We will follow the sanction as soon as the date and wording are confirmed."
