The British broadcaster was found to have committed a "serious breach" of industry standards by not revealing that the voice of a documentary about Gaza was the child of a Hamas representative, as ruled by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, saying there had been "a major oversight in relation to truthfulness".
The regulator has ordered the corporation to air a peak-time announcement about its findings.
"As this represents a serious breach of our rules, we are directing the BBC to air a statement of our conclusions against it on the BBC's second channel at 9pm, with a timing to be determined," the statement read.
'Potential to Undermine Confidence'
The watchdog's report said: "Our investigation determined that the programme's lack of disclosure that the narrator's father served in a position in the Hamas-run government was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been highly relevant to their assessment of the narrator and the information he presented.
"Confidence is at the heart of the bond between a media organization and its audience, especially for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to undermine the very considerable levels of credibility that the public would have placed in a factual film from the broadcaster about the Gaza conflict."
The documentary was pulled from iPlayer in the month of February after the narrator's familial connections came to light, and in July an internal BBC review determined it violated the corporation's journalistic standards on accuracy.
A representative for the broadcaster commented: "The authority's determination is in agreement with the conclusions of the corporation's inquiry, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in its entirety. We will follow the directive as soon as the timing and wording are determined."
