The BBC was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the presenter of a documentary about Gaza was the offspring 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 found that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, noting there had been "a major oversight in relation to accuracy".
The authority has directed the corporation to air a evening declaration about its conclusions.
"Given this constitutes a serious breach of our rules, we are ordering the BBC to broadcast a message of our determinations against it on BBC2 at nine o'clock in the evening, with a date to be confirmed," the regulator stated.
'Possibility to Erode Confidence'
The regulator's announcement stated: "Our probe found that the documentary's lack of disclosure that the voice's father occupied a role in the Hamas-run authority was materially misleading.
"It meant that the audience did not have essential details which may have been highly relevant to their judgment of the narrator and the details he provided.
"Trust is at the center of the relationship between a media organization and its audience, particularly for a public service broadcaster such as the BBC.
"This oversight had the possibility to undermine the significantly high degrees of trust that viewers would have put in a documentary produced by the BBC about the Gaza conflict."
The documentary was withdrawn from iPlayer in last February after the narrator's family links emerged, and in this past July an corporation's own inquiry determined it violated the corporation's editorial guidelines on factual correctness.
A BBC spokesperson stated: "The Ofcom ruling is in agreement with the findings of the internal assessment, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on factual correctness, which aligns with clause 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with Ofcom's decision in full. We will comply with the penalty as soon as the date and wording are finalised."
