The public service broadcaster engaged in a "major breach" of broadcasting rules by omitting to mention that the narrator of a documentary about the Gaza situation was the offspring of a Hamas administrator, as determined by regulatory body Ofcom.
An probe by the media regulator into Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a major oversight in relation to accuracy".
Ofcom has ordered the BBC to broadcast a prime-time statement about its decisions.
"Since this amounts to a serious breach of our code, we are ordering the corporation to transmit a announcement of our findings against it on BBC2 at 9pm, with a timing to be confirmed," the statement read.
'Possibility to Undermine Credibility'
The authority's announcement stated: "The inquiry we conducted concluded that the documentary's omission to reveal that the voice's father held a post in the Hamas-controlled government was substantially inaccurate.
"Consequently that the public did not have vital facts which may have been extremely pertinent to their evaluation of the presenter and the details he presented.
"Credibility is at the center of the connection between a broadcaster and its viewers, particularly for a state-funded media outlet such as the BBC.
"This oversight had the potential to erode the very considerable amounts of trust that viewers would have invested in a BBC factual programme about the Israel-Gaza war."
The film was pulled from the online platform in the month of February after the narrator's family links came to light, and in July an corporation's own inquiry found it breached the broadcaster's content policies on accuracy.
A representative for the broadcaster stated: "The authority's determination is in accordance with the results of the internal assessment, that there was a serious error in the film in relation to the corporation's content standards on truthfulness, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with the regulator's ruling in its entirety. We will follow the directive as soon as the timing and language are finalised."
