The public service broadcaster committed a "major breach" of media regulations by not revealing that the presenter of a documentary about the Gaza situation was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to accuracy".
The regulator has ordered the broadcaster to air a peak-time statement about its findings.
"Given this constitutes a significant violation of our code, we are directing the broadcaster to transmit a announcement of our findings against it on BBC2 at 21:00, with a schedule to be finalised," the regulator stated.
'Possibility to Damage Trust'
The authority's announcement stated: "Our probe concluded that the programme's lack of disclosure that the narrator's parent occupied a position in the Hamas-administered authority was materially misleading.
"This implied that the viewers did not have critical information which may have been extremely pertinent to their assessment of the voice and the information he shared.
"Confidence is at the heart of the connection between a media organization and its audience, particularly for a national broadcasting corporation such as the public broadcaster.
"This oversight had the risk to undermine the very considerable degrees of credibility that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The programme was removed from iPlayer in February after the narrator's personal associations came to light, and in this past July an corporation's own inquiry concluded it infringed the corporation's content policies on factual correctness.
A BBC spokesperson commented: "The regulator's decision is in line with the conclusions of Peter Johnston's review, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with the authority's determination in its entirety. We will follow the sanction as soon as the date and language are confirmed."
