The British broadcaster was found to have committed a "major breach" of broadcasting rules by omitting to mention that the narrator of a film about Gaza was the offspring of a Hamas representative, as determined by regulatory body Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a significant failing in relation to truthfulness".
The authority has directed the corporation to transmit a evening declaration about its findings.
"Since this amounts to a major infringement of our code, we are directing the corporation to broadcast a announcement of our determinations against it on BBC2 at 21:00, with a date to be confirmed," the regulator stated.
'Risk to Undermine Trust'
The authority's statement declared: "Our probe determined that the film's lack of disclosure that the voice's father served in a position in the Hamas-run government was materially misleading.
"It meant that the viewers did not have critical information which may have been extremely pertinent to their judgment of the presenter and the details he presented.
"Trust is at the center of the connection between a media organization and its viewers, especially for a public service broadcaster such as the BBC.
"This error had the possibility to damage the very considerable amounts of trust that the public would have placed in a BBC factual programme about the conflict in Gaza."
The programme was pulled from the online platform in the month of February after the narrator's familial connections emerged, and in this past July an corporation's own inquiry found it infringed the corporation's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The authority's determination is in line with the findings of Peter Johnston's review, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on truthfulness, which reflects Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with Ofcom's decision in complete. We will adhere to the penalty as soon as the timing and wording are finalised."
