The British broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the narrator of a documentary about the Gaza conflict was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The head of the BBC had previously apologised, saying there had been "a major oversight in relation to accuracy".
Ofcom has instructed the corporation to transmit a prime-time declaration about its decisions.
"Since this amounts to a major infringement of our regulations, we are directing the corporation to broadcast a announcement of our findings against it on BBC2 at 21:00, with a timing to be finalised," the statement read.
'Possibility to Erode Credibility'
The regulator's statement stated: "The inquiry we conducted determined that the programme's failure to disclose that the presenter's father served in a post in the Hamas-run administration was materially misleading.
"This implied that the viewers did not have vital facts which may have been very significant to their assessment of the presenter and the content he provided.
"Trust is at the center of the connection between a broadcaster and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the possibility to damage the exceptionally strong amounts of confidence that viewers would have invested in a BBC factual programme about the Israel-Gaza war."
The film was pulled from the online platform in February after the boy's familial connections emerged, and in the month of July an internal BBC review concluded it breached the corporation's content policies on truthfulness.
A corporation official stated: "The authority's determination is in line with the results of the corporation's inquiry, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to regulation 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with Ofcom's decision in full. We will follow the directive as soon as the schedule and wording are finalised."
