The public service broadcaster was found to have committed a "significant breach" of industry standards by failing to disclose that the presenter of a documentary about the Gaza conflict was the son of a Hamas representative, as ruled by regulatory body Ofcom.
An inquiry by the media regulator into Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The BBC's director general had already issued an apology, stating there had been "a significant failing in relation to accuracy".
Ofcom has directed the broadcaster to air a peak-time announcement about its conclusions.
"Given this constitutes a significant violation of our regulations, we are ordering the broadcaster to air a message of our findings against it on BBC2 at 21:00, with a schedule to be determined," the regulator stated.
The regulator's statement said: "The inquiry we conducted found that the programme's omission to reveal that the narrator's male guardian served in a position in the Hamas-run authority was materially misleading.
"This implied that the viewers did not have essential details which may have been highly relevant to their assessment of the voice and the details he presented.
"Credibility is at the core of the connection between a broadcaster and its viewers, particularly for a public service broadcaster such as the public broadcaster.
"This oversight had the potential to erode the exceptionally strong degrees of confidence that the public would have invested in a documentary produced by the BBC about the Gaza conflict."
The programme was pulled from the BBC's streaming service in last February after the boy's personal associations came to light, and in this past July an corporation's own inquiry found it breached the corporation's content policies on factual correctness.
A BBC spokesperson stated: "The Ofcom ruling is in agreement with the conclusions of Peter Johnston's review, that there was a serious error in the documentary in relation to the corporation's content standards on accuracy, which aligns with clause 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will follow the penalty as soon as the timing and wording are finalised."
