The public service broadcaster engaged in a "major breach" of media regulations by failing to disclose that the presenter of a film about Gaza was the child of a Hamas official, as ruled by regulatory body Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to factual correctness".
The regulator has ordered the corporation to transmit a peak-time announcement about its conclusions.
"Given this constitutes a serious breach of our code, we are ordering the BBC to air a statement of our determinations against it on BBC Two at 21:00, with a date to be finalised," the statement read.
'Risk to Damage Trust'
The regulator's announcement declared: "Our probe found that the documentary's lack of disclosure that the voice's male guardian held a role in the Hamas-controlled administration was substantially inaccurate.
"This implied that the audience did not have essential details which may have been extremely pertinent to their judgment of the presenter and the content he shared.
"Credibility is at the heart of the relationship between a broadcaster and its audience, notably for a national broadcasting corporation such as the public broadcaster.
"This failing had the potential to erode the very considerable amounts of confidence that audiences would have invested in a BBC factual programme about the conflict in Gaza."
The film was removed from the BBC's streaming service in last February after the presenter's personal associations were revealed, and in the month of July an broadcaster's internal assessment concluded it breached the corporation's content policies on truthfulness.
A corporation official said: "The regulator's decision is in agreement with the results of the corporation's inquiry, that there was a significant failing in the film in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the authority's determination in full. We will follow the sanction as soon as the timing and wording are determined."
