The public service broadcaster engaged in a "major breach" of media regulations by not revealing that the presenter of a film about the Gaza situation was the son of a Hamas administrator, as determined by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a significant failing in relation to truthfulness".
The regulator has instructed the corporation to air a evening announcement about its decisions.
"As this represents 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 21:00, with a date to be finalised," the statement read.
'Potential to Erode Confidence'
The watchdog's statement declared: "The inquiry we conducted concluded that the documentary's lack of disclosure that the presenter's father held a role in the Hamas-run authority was significantly deceptive.
"This implied that the viewers did not have critical information which may have been very significant to their evaluation of the voice and the content he shared.
"Trust is at the heart of the relationship between a media organization and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the very considerable levels of trust that viewers would have put in a documentary produced by the BBC about the Israel-Gaza war."
The film was pulled from the BBC's streaming service in the month of February after the presenter's personal associations were revealed, and in this past July an broadcaster's internal assessment concluded it violated the corporation's content policies on accuracy.
A BBC spokesperson said: "The regulator's decision is in agreement with the findings of the internal assessment, that there was a major oversight in the programme in relation to the corporation's content standards on truthfulness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with the authority's determination in its entirety. We will comply with the penalty as soon as the date and wording are confirmed."
