The British broadcaster committed a "significant breach" of broadcasting rules by omitting to mention that the voice of a documentary about Gaza was the child of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The BBC's director general had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The authority has directed the corporation to transmit a prime-time declaration about its decisions.
"Given this constitutes a significant violation of our rules, we are instructing the BBC to transmit a message of our findings against it on the BBC's second channel at 21:00, with a schedule to be determined," it said.
'Potential to Undermine Credibility'
The regulator's announcement stated: "Our investigation found that the documentary's omission to reveal that the voice's male guardian served in a role in the Hamas-administered administration was materially misleading.
"Consequently that the viewers did not have critical information which may have been extremely pertinent to their judgment of the narrator and the content he presented.
"Credibility is at the heart of the relationship between a broadcaster and its audience, notably for a public service broadcaster such as the BBC.
"This oversight had the risk to erode the significantly high levels of trust that the public would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was withdrawn from iPlayer in the month of February after the narrator's family links were revealed, and in this past July an broadcaster's internal assessment found it infringed the organization's content policies on factual correctness.
A representative for the broadcaster said: "The Ofcom ruling is in accordance with the results of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on truthfulness, which aligns with Rule 2.2 of the regulator's media standards.
"We have apologised for this and we agree with Ofcom's decision in its entirety. We will adhere to the directive as soon as the schedule and language are finalised."
