The British broadcaster was found to have committed a "major breach" of media regulations by omitting to mention that the voice of a documentary about the Gaza conflict was the offspring of a Hamas representative, as ruled 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 "significantly deceptive".
The chief executive of the broadcaster had previously apologised, saying there had been "a major oversight in relation to factual correctness".
Ofcom has instructed the broadcaster to broadcast a peak-time declaration about its decisions.
"As this represents a serious breach of our code, we are ordering the broadcaster to broadcast a statement of our conclusions against it on BBC2 at 9pm, with a date to be finalised," it said.
'Risk to Erode Confidence'
The authority's announcement stated: "Our probe determined that the programme's omission to reveal that the narrator's male guardian held a position in the Hamas-run administration was significantly deceptive.
"This implied that the audience did not have critical information which may have been extremely pertinent to their assessment of the narrator and the information he provided.
"Trust is at the heart of the connection between a media organization and its public, notably for a state-funded media outlet such as the public broadcaster.
"This error had the potential to damage the significantly high degrees of credibility that viewers would have placed in a documentary produced by the BBC about the conflict in Gaza."
The documentary was pulled from the online platform in February after the boy's personal associations emerged, and in this past July an corporation's own inquiry determined it violated the corporation's journalistic standards on accuracy.
A representative for the broadcaster said: "The Ofcom ruling is in line with the results of Peter Johnston's review, that there was a serious error in the programme in relation to the corporation's content standards on accuracy, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we comply with Ofcom's decision in complete. We will comply with the penalty as soon as the schedule and wording are determined."
