The public service broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the presenter of a film about the Gaza conflict was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by the media regulator into Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The head of the BBC had earlier expressed regret, noting there had been "a major oversight in relation to factual correctness".
Ofcom has instructed the BBC to broadcast a prime-time statement about its findings.
"Given this constitutes a significant violation of our code, we are directing the BBC to air a statement of our findings against it on BBC2 at 9pm, with a timing to be confirmed," the statement read.
'Risk to Erode Confidence'
The watchdog's announcement declared: "Our probe found that the film's omission to reveal that the narrator's male guardian served in a role in the Hamas-run government was substantially inaccurate.
"Consequently that the viewers did not have essential details which may have been highly relevant to their evaluation of the narrator and the details he provided.
"Credibility is at the core of the relationship between a media organization and its audience, notably for a public service broadcaster such as the BBC.
"This oversight had the possibility to damage the exceptionally strong levels of credibility that the public 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 last February after the narrator's personal associations came to light, and in the month of July an internal BBC review concluded it infringed the organization's editorial guidelines on accuracy.
A corporation official said: "The authority's determination is in accordance with the conclusions of Peter Johnston's review, that there was a significant failing in the programme in relation to the corporation's content standards on factual correctness, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the authority's determination in complete. We will adhere to the directive as soon as the schedule and wording are finalised."
