The British broadcaster was found to have committed a "major breach" of media regulations by failing to disclose that the voice of a documentary about the Gaza situation was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The head of the BBC had already issued an apology, stating there had been "a significant failing in relation to accuracy".
The regulator has instructed the corporation to air a prime-time statement about its decisions.
"Given this constitutes a serious breach of our code, we are directing the corporation to transmit a statement of our findings against it on BBC Two at nine o'clock in the evening, with a date to be determined," it said.
'Risk to Erode Credibility'
The watchdog's report declared: "The inquiry we conducted determined that the documentary's omission to reveal that the narrator's male guardian served in a post in the Hamas-run government was materially misleading.
"It meant that the audience did not have critical information which may have been very significant to their judgment of the presenter and the details he presented.
"Confidence is at the center of the relationship between a television network and its public, particularly for a state-funded media outlet such as the BBC.
"This oversight had the possibility to undermine the very considerable amounts of credibility that viewers would have invested in a factual film from the broadcaster about the conflict in Gaza."
The documentary was pulled from the BBC's streaming service in the month of February after the narrator's personal associations came to light, and in this past July an corporation's own inquiry concluded it breached the corporation's content policies on truthfulness.
A corporation official stated: "The regulator's decision is in accordance with the conclusions of the internal assessment, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on truthfulness, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we comply with the regulator's ruling in full. We will adhere to the directive as soon as the schedule and language are finalised."
