The public service broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the narrator of a programme about Gaza was the son of a Hamas official, according to UK media regulator Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to factual correctness".
Ofcom has ordered the BBC to air a peak-time statement about its findings.
"Since this amounts to a major infringement of our code, we are ordering the broadcaster to air a statement of our determinations against it on BBC2 at nine o'clock in the evening, with a timing to be determined," the statement read.
'Risk to Damage Credibility'
The regulator's announcement declared: "Our investigation determined that the film's lack of disclosure that the voice's parent occupied a position in the Hamas-controlled authority was materially misleading.
"Consequently that the public did not have critical information which may have been very significant to their assessment of the narrator and the details he provided.
"Confidence is at the center of the relationship between a broadcaster and its audience, notably for a national broadcasting corporation such as the public broadcaster.
"This oversight had the potential to erode the very considerable levels of trust that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was withdrawn from iPlayer in February after the presenter's personal associations were revealed, and in this past July an broadcaster's internal assessment determined it violated the corporation's content policies on truthfulness.
A corporation official stated: "The authority's determination is in line with the results of Peter Johnston's review, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on truthfulness, which aligns with regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we accept the authority's determination in complete. We will comply with the penalty as soon as the date and wording are determined."
