The British broadcaster was found to have committed a "serious breach" of media regulations by omitting to mention that the voice of a documentary about the Gaza situation was the offspring of a Hamas representative, as ruled by regulatory body Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The head of the BBC had earlier expressed regret, noting there had been "a significant failing in relation to accuracy".
Ofcom has ordered the BBC to air a evening statement about its decisions.
"As this represents a significant violation of our code, we are ordering the BBC to air a message of our determinations against it on BBC Two at 9pm, with a schedule to be confirmed," the regulator stated.
'Risk to Damage Confidence'
The authority's statement stated: "Our investigation determined that the documentary's lack of disclosure that the narrator's father held a post in the Hamas-run authority was materially misleading.
"This implied that the audience did not have critical information which may have been extremely pertinent to their judgment of the voice and the details he shared.
"Confidence is at the core of the connection between a media organization and its audience, particularly for a state-funded media outlet such as the BBC.
"This oversight had the potential to damage the exceptionally strong degrees of credibility that audiences would have placed in a factual film from the broadcaster about the conflict in Gaza."
The documentary was withdrawn from the online platform in last February after the narrator's familial connections were revealed, and in this past July an corporation's own inquiry found it violated the organization's journalistic standards on truthfulness.
A corporation official stated: "The Ofcom ruling is in agreement with the findings of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on accuracy, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the authority's determination in its entirety. We will comply with the directive as soon as the date and wording are confirmed."
