The BBC committed a "serious breach" of media regulations by failing to disclose that the presenter of a programme about Gaza was the son of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, noting there had been "a significant failing in relation to factual correctness".
Ofcom has directed the corporation to air a evening declaration about its decisions.
"Given this constitutes a serious breach of our code, we are ordering the corporation to transmit a message of our determinations against it on the BBC's second channel at 21:00, with a schedule to be confirmed," the regulator stated.
'Potential to Damage Credibility'
The authority's statement said: "Our probe determined that the film's omission to reveal that the voice's male guardian occupied a position in the Hamas-controlled government was materially misleading.
"This implied that the viewers did not have critical information which may have been highly relevant to their judgment of the narrator and the details he provided.
"Credibility is at the core of the connection between a broadcaster and its viewers, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the exceptionally strong degrees of confidence that the public would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was withdrawn from the online platform in the month of February after the narrator's personal associations were revealed, and in this past July an internal BBC review found it violated the broadcaster's content policies on truthfulness.
A BBC spokesperson stated: "The Ofcom ruling is in accordance with the conclusions of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on accuracy, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in complete. We will follow the sanction as soon as the date and wording are confirmed."
