The public service broadcaster was found to have committed a "major breach" of industry standards by not revealing that the narrator of a documentary about the Gaza situation was the offspring of a Hamas representative, according to UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The BBC's director general had already issued an apology, noting there had been "a major oversight in relation to accuracy".
Ofcom has ordered the broadcaster to transmit a evening statement about its findings.
"Since this amounts to a serious breach of our regulations, we are instructing the broadcaster to transmit a message of our findings against it on BBC Two at nine o'clock in the evening, with a date to be determined," the regulator stated.
'Risk to Erode Confidence'
The regulator's report stated: "The inquiry we conducted determined that the documentary's failure to disclose that the voice's father held a role in the Hamas-controlled administration was materially misleading.
"This implied that the viewers did not have critical information which may have been very significant to their assessment of the presenter and the information he presented.
"Credibility is at the center of the bond between a television network and its public, particularly for a national broadcasting corporation such as the BBC.
"This failing had the possibility to erode the exceptionally strong levels of credibility that viewers would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The film was withdrawn from the BBC's streaming service in February after the presenter's personal associations were revealed, and in July an internal BBC review found it breached the organization's journalistic standards on truthfulness.
A corporation official said: "The regulator's decision is in agreement with the findings of the internal assessment, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret 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 finalised."
