The public service broadcaster committed a "major breach" of broadcasting rules by omitting to mention that the presenter of a film about the Gaza conflict was the offspring of a Hamas official, as determined by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a serious error in relation to truthfulness".
Ofcom has directed the corporation to transmit a prime-time statement about its conclusions.
"Given this constitutes a major infringement of our regulations, we are instructing the BBC to air a statement of our findings against it on the BBC's second channel at nine o'clock in the evening, with a timing to be finalised," the regulator stated.
'Risk to Erode Trust'
The authority's statement said: "The inquiry we conducted determined that the documentary's failure to disclose that the voice's male guardian served in a post in the Hamas-run administration was substantially inaccurate.
"Consequently that the audience did not have critical information which may have been extremely pertinent to their assessment of the narrator and the content he shared.
"Trust is at the core of the relationship between a media organization and its audience, especially for a state-funded media outlet such as the public broadcaster.
"This error had the potential to undermine the very considerable degrees of trust that viewers would have put in a BBC factual programme about the Gaza conflict."
The documentary was pulled from iPlayer in the month of February after the presenter's personal associations emerged, and in the month of July an broadcaster's internal assessment found it breached the broadcaster's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The Ofcom ruling is in agreement with the findings of the corporation's inquiry, that there was a serious error in the programme in relation to the corporation's content standards on factual correctness, which corresponds to Rule 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 adhere to the directive as soon as the date and language are finalised."
