The public service broadcaster committed a "serious breach" of broadcasting rules by not revealing that the presenter of a programme about the Gaza situation was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The head of the BBC had earlier expressed regret, noting there had been "a major oversight in relation to accuracy".
Ofcom has directed the broadcaster to transmit a prime-time announcement about its conclusions.
"Given this constitutes a serious breach of our code, we are ordering the broadcaster to transmit a statement of our determinations against it on BBC2 at nine o'clock in the evening, with a timing to be determined," the regulator stated.
'Possibility to Damage Credibility'
The regulator's announcement said: "Our investigation concluded that the film's lack of disclosure that the narrator's father held a role in the Hamas-run authority was materially misleading.
"It meant that the public did not have vital facts which may have been highly relevant to their evaluation of the voice and the information he presented.
"Confidence is at the core of the connection between a television network and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This error had the potential to undermine the exceptionally strong levels of trust that the public would have placed in a BBC factual programme about the conflict in Gaza."
The film was removed from the BBC's streaming service in last February after the narrator's familial connections emerged, and in this past July an internal BBC review concluded it infringed the organization's journalistic standards on accuracy.
A representative for the broadcaster commented: "The Ofcom ruling is in accordance with the findings of Peter Johnston's review, that there was a significant failing in the film in relation to the corporation's content standards on truthfulness, which corresponds to Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with Ofcom's decision in its entirety. We will adhere to the directive as soon as the schedule and wording are confirmed."
