The British broadcaster committed a "major breach" of media regulations by omitting to mention that the presenter of a programme about the Gaza situation was the son of a Hamas representative, as determined by British broadcasting authority Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The BBC's director general had already issued an apology, noting there had been "a significant failing in relation to truthfulness".
The regulator has instructed the broadcaster to transmit a evening declaration about its findings.
"Since this amounts to a serious breach of our regulations, we are instructing the BBC to transmit a announcement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be finalised," the statement read.
'Potential to Damage Confidence'
The regulator's report stated: "The inquiry we conducted determined that the programme's lack of disclosure that the voice's father held a post in the Hamas-controlled government was materially misleading.
"Consequently that the public did not have critical information which may have been highly relevant to their judgment of the presenter and the information he shared.
"Trust is at the center of the bond between a broadcaster and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the possibility to undermine the exceptionally strong amounts of credibility that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The documentary was pulled from the BBC's streaming service in February after the boy's family links emerged, and in July an internal BBC review determined it infringed the broadcaster's editorial guidelines on truthfulness.
A corporation official stated: "The authority's determination is in agreement with the findings of the corporation's inquiry, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on accuracy, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the authority's determination in its entirety. We will comply with the directive as soon as the date and wording are finalised."
