The British broadcaster committed a "major breach" of broadcasting rules by failing to disclose that the presenter of a film about Gaza was the offspring of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, noting there had been "a major oversight in relation to truthfulness".
Ofcom has directed the corporation to air a prime-time statement about its conclusions.
"As this represents a major infringement of our code, we are directing the broadcaster to air a statement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be determined," the regulator stated.
'Potential to Undermine Credibility'
The authority's announcement declared: "Our probe determined that the documentary's lack of disclosure that the voice's father held a position in the Hamas-run authority was materially misleading.
"This implied that the public did not have vital facts which may have been extremely pertinent to their evaluation of the presenter and the details he presented.
"Credibility is at the heart of the relationship between a broadcaster and its viewers, particularly for a national broadcasting corporation such as the public broadcaster.
"This oversight had the risk to undermine the very considerable degrees of confidence that audiences would have placed in a documentary produced by the BBC about the conflict in Gaza."
The programme was withdrawn from the online platform in February after the boy's family links came to light, and in this past July an corporation's own inquiry found it violated the organization's content policies on truthfulness.
A representative for the broadcaster commented: "The regulator's decision is in accordance with the findings of Peter Johnston's review, that there was a serious error in the film in relation to the corporation's content standards on factual correctness, which aligns with clause 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the authority's determination in full. We will follow the sanction as soon as the date and wording are confirmed."
