The British broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the presenter of a programme about Gaza was the offspring of a Hamas representative, as ruled by UK media regulator Ofcom.
An inquiry by the media regulator into Gaza: How to Survive a Warzone has found that the documentary was "significantly deceptive".
The BBC's director general had already issued an apology, saying there had been "a significant failing in relation to factual correctness".
The authority has directed the BBC to broadcast a peak-time announcement about its conclusions.
"As this represents a major infringement of our regulations, we are instructing the broadcaster to transmit a statement of our determinations against it on the BBC's second channel at 21:00, with a schedule to be confirmed," the statement read.
'Risk to Erode Trust'
The watchdog's announcement said: "Our probe concluded that the documentary's omission to reveal that the narrator's father held a position in the Hamas-administered government was substantially inaccurate.
"This implied that the viewers did not have critical information which may have been extremely pertinent to their assessment of the voice and the information he shared.
"Confidence is at the core of the relationship between a broadcaster and its public, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the possibility to erode the exceptionally strong amounts of confidence that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was withdrawn from the BBC's streaming service in the month of February after the presenter's personal associations emerged, and in the month of July an internal BBC review found it breached the corporation's journalistic standards on accuracy.
A BBC spokesperson stated: "The Ofcom ruling is in accordance with the results of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the regulator's ruling in complete. We will adhere to the directive as soon as the schedule and wording are determined."
