The British broadcaster committed a "major breach" of industry standards by omitting to mention that the narrator of a documentary about the Gaza situation was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a major oversight in relation to accuracy".
The authority has ordered the corporation to broadcast a prime-time statement about its conclusions.
"As this represents a major infringement of our code, we are instructing the corporation to air a announcement of our conclusions against it on BBC2 at nine o'clock in the evening, with a schedule to be determined," the statement read.
'Potential to Erode Trust'
The regulator's report said: "Our investigation concluded that the documentary's lack of disclosure that the presenter's father served in a position in the Hamas-controlled government was materially misleading.
"This implied that the public did not have essential details which may have been very significant to their judgment of the voice and the details he shared.
"Confidence is at the heart of the relationship between a media organization and its audience, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the potential to erode the very considerable levels of credibility that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The programme was withdrawn from iPlayer in February after the narrator's personal associations were revealed, and in this past July an broadcaster's internal assessment concluded it breached the organization's editorial guidelines on factual correctness.
A corporation official stated: "The regulator's decision is in accordance with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with Ofcom's decision in its entirety. We will comply with the sanction as soon as the timing and wording are finalised."
