The public service broadcaster was found to have committed a "major breach" of media regulations by failing to disclose that the presenter of a documentary about the Gaza situation was the offspring of a Hamas representative, as determined by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The head of the BBC had already issued an apology, stating there had been "a serious error in relation to accuracy".
The authority has ordered the broadcaster to transmit a prime-time statement about its conclusions.
"Since this amounts to a major infringement of our rules, we are ordering the BBC to transmit a message of our findings against it on the BBC's second channel at 9pm, with a date to be finalised," the regulator stated.
'Risk to Damage Confidence'
The authority's announcement stated: "Our probe found that the documentary's failure to disclose that the narrator's father occupied a position in the Hamas-run administration was materially misleading.
"Consequently that the viewers did not have vital facts which may have been highly relevant to their assessment of the narrator and the content he shared.
"Credibility is at the heart of the connection between a television network and its audience, especially for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to undermine the very considerable levels of credibility that the public would have put in a factual film from the broadcaster about the Israel-Gaza war."
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 found it infringed the organization's journalistic standards on factual correctness.
A BBC spokesperson said: "The authority's determination is in agreement with the results of Peter Johnston's review, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept the authority's determination in full. We will comply with the directive as soon as the schedule and wording are finalised."
