The British broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the narrator of a film about the Gaza situation was the son of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, noting there had been "a significant failing in relation to accuracy".
The authority has ordered the corporation to transmit a prime-time statement about its conclusions.
"As this represents a significant violation of our rules, 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 schedule to be confirmed," it said.
'Risk to Undermine Credibility'
The authority's statement stated: "The inquiry we conducted found that the documentary's failure to disclose that the voice's father held a role in the Hamas-controlled government was materially misleading.
"It meant that the audience did not have critical information which may have been highly relevant to their judgment of the narrator and the content he provided.
"Credibility is at the center of the relationship between a media organization and its audience, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the possibility to damage the exceptionally strong levels of trust that the public would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The programme was pulled from the BBC's streaming service in last February after the boy's family links emerged, and in this past July an internal BBC review concluded it violated the broadcaster's content policies on factual correctness.
A corporation official said: "The authority's determination is in accordance with the findings of the corporation's inquiry, that there was a serious error in the film in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in its entirety. We will comply with the directive as soon as the timing and wording are confirmed."
