The British broadcaster committed a "significant breach" of industry standards by omitting to mention that the voice of a programme about Gaza was the offspring of a Hamas official, as determined by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, noting there had been "a significant failing in relation to factual correctness".
Ofcom has directed the BBC to transmit a peak-time announcement about its conclusions.
"Since this amounts to a major infringement of our code, we are directing the corporation to broadcast a statement of our conclusions against it on BBC Two at 21:00, with a date to be confirmed," the regulator stated.
'Risk to Damage Confidence'
The watchdog's statement stated: "The inquiry we conducted determined that the programme's lack of disclosure that the narrator's male guardian served in a role in the Hamas-controlled administration was significantly deceptive.
"It meant that the public did not have essential details which may have been very significant to their assessment of the voice and the details he shared.
"Confidence is at the center of the bond between a broadcaster and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the possibility to erode the very considerable levels of confidence that the public would have put in a BBC factual programme about the Gaza conflict."
The film was pulled from iPlayer in February after the boy's family links came to light, and in this past July an broadcaster's internal assessment concluded it infringed the broadcaster's journalistic standards on factual correctness.
A corporation official commented: "The regulator's decision is in accordance with the findings of Peter Johnston's review, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on accuracy, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with the authority's determination in its entirety. We will adhere to the directive as soon as the date and wording are finalised."
