The public service broadcaster committed a "major breach" of media regulations by not revealing that the narrator of a documentary about the Gaza conflict was the son of a Hamas representative, as determined by regulatory body Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to factual correctness".
Ofcom has ordered the corporation to broadcast a prime-time statement about its conclusions.
"Since this amounts to a serious breach of our rules, we are ordering the corporation to broadcast a statement of our conclusions against it on BBC2 at 9pm, with a timing to be finalised," it said.
'Risk to Erode Trust'
The regulator's statement said: "Our probe determined that the film's lack of disclosure that the presenter's father served in a post in the Hamas-administered administration was substantially inaccurate.
"Consequently that the viewers did not have critical information which may have been extremely pertinent to their evaluation of the presenter and the content he shared.
"Trust is at the center of the connection between a broadcaster and its audience, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the possibility to damage the exceptionally strong levels of trust that the public would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was removed from iPlayer in last February after the narrator's family links came to light, and in July an corporation's own inquiry concluded it violated the corporation's journalistic standards on accuracy.
A representative for the broadcaster said: "The authority's determination is in accordance with the conclusions of Peter Johnston's review, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on accuracy, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in full. We will follow the penalty as soon as the date and wording are confirmed."
