The British broadcaster engaged in a "serious breach" of media regulations by omitting to mention that the narrator of a programme about the Gaza conflict was the child of a Hamas representative, as ruled by UK media regulator Ofcom.
An probe by Ofcom into Gaza: How to Survive a Warzone has found that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, noting there had been "a major oversight in relation to truthfulness".
The regulator has directed the corporation to transmit a peak-time announcement about its findings.
"Since this amounts to a major infringement of our code, we are instructing the corporation to broadcast a announcement of our conclusions against it on BBC Two at 21:00, with a schedule to be finalised," the statement read.
'Potential to Damage Trust'
The regulator's report stated: "Our probe concluded that the film's failure to disclose that the voice's father served in a position in the Hamas-run government was materially misleading.
"This implied that the viewers did not have critical information which may have been highly relevant to their evaluation of the voice and the details he shared.
"Credibility is at the heart of the relationship between a media organization and its public, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the potential to erode the exceptionally strong amounts of credibility that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The film was pulled from the online platform in the month of February after the presenter's familial connections emerged, and in the month of July an corporation's own inquiry determined it infringed the corporation's journalistic standards on accuracy.
A BBC spokesperson stated: "The Ofcom ruling is in line with the results of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on truthfulness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we comply with the regulator's ruling in its entirety. We will follow the directive as soon as the schedule and wording are determined."
