The public service broadcaster was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the voice of a film about the Gaza situation was the son of a Hamas representative, as determined by regulatory body Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a significant failing in relation to accuracy".
The regulator has instructed the BBC to air a peak-time announcement about its decisions.
"Given this constitutes a significant violation of our code, we are directing the broadcaster to air a announcement of our conclusions against it on BBC2 at 9pm, with a timing to be confirmed," the regulator stated.
'Risk to Erode Confidence'
The regulator's report said: "Our probe found that the programme's failure to disclose that the narrator's parent served in a post in the Hamas-controlled authority was substantially inaccurate.
"This implied that the public did not have essential details which may have been very significant to their evaluation of the narrator and the information he shared.
"Trust is at the heart of the relationship between a media organization and its viewers, especially for a public service broadcaster such as the BBC.
"This failing had the risk to erode the very considerable amounts of confidence that viewers would have placed in a BBC factual programme about the Gaza conflict."
The film was pulled from the online platform in the month of February after the presenter's personal associations emerged, and in the month of July an corporation's own inquiry concluded it violated the broadcaster's editorial guidelines on accuracy.
A representative for the broadcaster said: "The authority's determination is in agreement with the results of the internal assessment, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on truthfulness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in full. We will adhere to the sanction as soon as the date and wording are confirmed."
