The public service broadcaster committed a "significant breach" of broadcasting rules by omitting to mention that the voice of a film about the Gaza situation was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, noting there had been "a major oversight in relation to accuracy".
The authority has directed the BBC to air a peak-time announcement about its decisions.
"Given this constitutes a significant violation of our regulations, we are ordering the BBC to air a message of our determinations against it on BBC Two at 9pm, with a timing to be confirmed," the statement read.
'Possibility to Undermine Credibility'
The regulator's statement declared: "The inquiry we conducted concluded that the film's lack of disclosure that the presenter's male guardian occupied a role in the Hamas-controlled government was substantially inaccurate.
"Consequently that the audience did not have vital facts which may have been highly relevant to their judgment of the presenter and the information he shared.
"Confidence is at the center of the connection between a media organization and its public, particularly for a public service broadcaster such as the BBC.
"This failing had the possibility to erode the significantly high levels of trust that viewers would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The film was pulled from the BBC's streaming service in the month of February after the presenter's family links were revealed, and in this past July an corporation's own inquiry concluded it breached the corporation's editorial guidelines on accuracy.
A representative for the broadcaster stated: "The Ofcom ruling is in line with the findings of the internal assessment, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on accuracy, which reflects regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with Ofcom's decision in its entirety. We will adhere to the directive as soon as the timing and wording are finalised."
