The public service broadcaster committed a "significant breach" of industry standards by failing to disclose that the narrator of a film about the Gaza situation was the child of a Hamas administrator, according to UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, stating there had been "a significant failing in relation to accuracy".
Ofcom has directed the broadcaster to broadcast a prime-time statement about its decisions.
"As this represents a serious breach of our rules, we are ordering the broadcaster to broadcast a announcement of our conclusions against it on BBC2 at nine o'clock in the evening, with a date to be confirmed," the regulator stated.
'Potential to Damage Credibility'
The authority's report said: "The inquiry we conducted determined that the film's omission to reveal that the presenter's father served in a role in the Hamas-administered authority was materially misleading.
"This implied that the viewers did not have vital facts which may have been highly relevant to their judgment of the presenter and the details he provided.
"Confidence is at the center of the connection between a broadcaster and its audience, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the potential to erode the exceptionally strong levels of trust that the public would have invested in a BBC factual programme about the conflict in Gaza."
The film was pulled from iPlayer in February after the narrator's family links emerged, and in this past July an broadcaster's internal assessment concluded it infringed the organization's journalistic standards on factual correctness.
A BBC spokesperson said: "The regulator's decision is in agreement with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with the authority's determination in its entirety. We will comply with the penalty as soon as the schedule and wording are determined."
