The public service broadcaster was found to have committed a "major breach" of broadcasting rules by omitting to mention that the presenter of a programme about the Gaza conflict was the son of a Hamas representative, as determined by regulatory body Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The head of the BBC had already issued an apology, stating there had been "a significant failing in relation to truthfulness".
The authority has ordered the BBC to transmit a prime-time declaration about its conclusions.
"As this represents a serious breach of our code, we are directing the broadcaster to transmit a message of our determinations against it on BBC Two at nine o'clock in the evening, with a schedule to be confirmed," the regulator stated.
'Potential to Undermine Trust'
The authority's report declared: "The inquiry we conducted concluded that the programme's failure to disclose that the narrator's male guardian held a position in the Hamas-controlled government was significantly deceptive.
"It meant that the public did not have vital facts which may have been highly relevant to their evaluation of the presenter and the information he presented.
"Confidence is at the heart of the bond between a television network and its viewers, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the risk to undermine the very considerable amounts of credibility that viewers would have invested in a factual film from the broadcaster about the conflict in Gaza."
The film was pulled from iPlayer in the month of February after the presenter's familial connections emerged, and in this past July an internal BBC review found it breached the broadcaster's editorial guidelines on factual correctness.
A corporation official commented: "The regulator's decision is in line with the findings of the internal assessment, that there was a significant failing in the programme in relation to the corporation's content standards on truthfulness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept the authority's determination in its entirety. We will comply with the directive as soon as the date and wording are finalised."
