The public service broadcaster was found to have committed a "serious breach" of media regulations by not revealing that the presenter of a film about Gaza was the offspring of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An investigation by Ofcom into Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to factual correctness".
The regulator has instructed the corporation to transmit a peak-time declaration about its findings.
"Since this amounts to a significant violation of our code, we are ordering the broadcaster to broadcast a statement of our determinations against it on BBC2 at 21:00, with a date to be finalised," the statement read.
'Risk to Undermine Confidence'
The regulator's announcement stated: "The inquiry we conducted found that the film's failure to disclose that the voice's male guardian occupied a position in the Hamas-run government was materially misleading.
"This implied that the public did not have essential details which may have been extremely pertinent to their judgment of the voice and the content he provided.
"Confidence is at the core of the bond between a broadcaster and its viewers, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the risk to damage the exceptionally strong amounts of confidence that viewers would have placed in a factual film from the broadcaster about the Gaza conflict."
The programme was pulled from the BBC's streaming service in the month of February after the narrator's personal associations emerged, and in the month of July an broadcaster's internal assessment concluded it breached the broadcaster's journalistic standards on accuracy.
A representative for the broadcaster said: "The Ofcom ruling is in line with the conclusions of the corporation's inquiry, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on truthfulness, which aligns with clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept the regulator's ruling in its entirety. We will comply with the directive as soon as the schedule and wording are confirmed."
