The British broadcaster was found to have committed a "major breach" of broadcasting rules by omitting to mention that the narrator of a documentary about Gaza was the offspring of a Hamas administrator, as ruled by UK media regulator Ofcom.
An inquiry by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, noting there had been "a major oversight in relation to truthfulness".
The regulator has instructed the broadcaster to broadcast a evening announcement about its decisions.
"Given this constitutes a major infringement of our regulations, we are ordering the broadcaster to transmit a message of our determinations against it on the BBC's second channel at 9pm, with a schedule to be confirmed," it said.
'Possibility to Damage Trust'
The authority's statement declared: "Our probe concluded that the film's omission to reveal that the narrator's male guardian occupied a role in the Hamas-run authority was materially misleading.
"Consequently that the audience did not have vital facts which may have been highly relevant to their judgment of the narrator and the information he presented.
"Trust is at the heart of the bond between a broadcaster and its audience, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the exceptionally strong levels of trust that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The documentary was pulled from the online platform in February after the boy's familial connections came to light, and in the month of July an corporation's own inquiry found it breached the organization's editorial guidelines on truthfulness.
A BBC spokesperson stated: "The regulator's decision is in agreement with the findings of the corporation's inquiry, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on accuracy, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with the authority's determination in its entirety. We will follow the penalty as soon as the date and wording are confirmed."
