The public service broadcaster committed a "significant breach" of broadcasting rules by failing to disclose that the narrator of a documentary about the Gaza situation was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by the broadcasting watchdog into Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The BBC's director general had earlier expressed regret, saying there had been "a major oversight in relation to factual correctness".
The authority has directed the BBC to air a prime-time statement about its findings.
"Since this amounts to a major infringement of our code, we are directing the BBC to broadcast a announcement of our findings against it on BBC2 at 9pm, with a date to be determined," the regulator stated.
'Risk to Undermine Credibility'
The watchdog's statement stated: "Our investigation found that the documentary's failure to disclose that the narrator's parent served in a position in the Hamas-run administration was substantially inaccurate.
"It meant that the viewers did not have vital facts which may have been highly relevant to their evaluation of the voice and the information he presented.
"Credibility is at the heart of the relationship between a broadcaster and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the potential to damage the exceptionally strong levels of confidence that audiences would have invested in a BBC factual programme about the conflict in Gaza."
The programme was pulled from iPlayer in the month of February after the presenter's familial connections came to light, and in July an corporation's own inquiry concluded it infringed the organization's content policies on factual correctness.
A BBC spokesperson commented: "The authority's determination is in accordance with the conclusions of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on factual correctness, which aligns with regulation 2.2 of the regulator's media standards.
"We have apologised for this and we agree with the regulator's ruling in complete. We will follow the directive as soon as the schedule and language are confirmed."
