The public service broadcaster was found to have committed a "serious breach" of media regulations by omitting to mention that the voice of a programme about Gaza was the son of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The head of the BBC had already issued an apology, noting there had been "a significant failing in relation to truthfulness".
The regulator has instructed the corporation to air a prime-time statement about its findings.
"As this represents a major infringement of our regulations, we are instructing the BBC to air a announcement of our determinations against it on BBC2 at 9pm, with a schedule to be determined," the statement read.
'Potential to Erode Confidence'
The watchdog's statement declared: "Our probe determined that the film's failure to disclose that the presenter's male guardian held a position in the Hamas-administered government was significantly deceptive.
"Consequently that the audience did not have essential details which may have been highly relevant to their assessment of the voice and the information he provided.
"Confidence is at the center of the bond between a television network and its viewers, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the potential to erode the significantly high degrees of credibility that audiences would have invested in a BBC factual programme about the conflict in Gaza."
The documentary was withdrawn from the BBC's streaming service in the month of February after the presenter's personal associations were revealed, and in this past July an internal BBC review concluded it breached the corporation's content policies on accuracy.
A BBC spokesperson said: "The authority's determination is in accordance with the conclusions of the corporation's inquiry, that there was a major oversight in the documentary in relation to the corporation's content standards on factual correctness, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will comply with the directive as soon as the date and language are determined."
