The British broadcaster was found to have committed a "major breach" of media regulations by failing to disclose that the narrator of a documentary about the Gaza conflict was the child of a Hamas administrator, as ruled by UK media regulator Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, saying there had been "a major oversight in relation to factual correctness".
Ofcom has directed the BBC to broadcast a peak-time announcement about its decisions.
"Given this constitutes a major infringement of our code, we are directing the corporation to broadcast a announcement of our findings against it on BBC Two at 9pm, with a timing to be determined," the regulator stated.
'Possibility to Erode Confidence'
The regulator's report said: "The inquiry we conducted concluded that the programme's failure to disclose that the narrator's father held a post in the Hamas-run administration was materially misleading.
"It meant that the public did not have critical information which may have been very significant to their evaluation of the voice and the details he provided.
"Trust is at the center of the relationship between a broadcaster and its public, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the potential to damage the exceptionally strong levels of confidence that audiences would have invested in a documentary produced by the BBC about the conflict in Gaza."
The film was withdrawn from the BBC's streaming service in February after the narrator's family links were revealed, and in July an corporation's own inquiry determined it infringed the organization's content policies on truthfulness.
A representative for the broadcaster commented: "The regulator's decision is in agreement with the findings of the corporation's inquiry, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with the regulator's ruling in its entirety. We will adhere to the directive as soon as the schedule and language are finalised."
