The British broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the voice of a documentary about Gaza was the son of a Hamas representative, as ruled by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, saying there had been "a significant failing in relation to truthfulness".
The regulator has ordered the BBC to air a peak-time statement about its decisions.
"Since this amounts to a significant violation of our code, we are instructing the BBC to transmit a announcement of our conclusions against it on BBC Two at nine o'clock in the evening, with a timing to be determined," it said.
'Risk to Damage Trust'
The authority's announcement stated: "The inquiry we conducted found that the programme's lack of disclosure that the voice's father served in a position in the Hamas-administered administration was significantly deceptive.
"This implied that the audience did not have vital facts which may have been highly relevant to their evaluation of the narrator and the content he provided.
"Credibility is at the center of the bond between a broadcaster and its audience, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the possibility to damage the exceptionally strong amounts of trust that the public would have put in a factual film from the broadcaster about the conflict in Gaza."
The film was removed from iPlayer in the month of February after the boy's personal associations emerged, and in this past July an internal BBC review concluded it infringed the corporation's editorial guidelines on factual correctness.
A corporation official commented: "The authority's determination is in agreement with the results of the internal assessment, that there was a serious error in the documentary in relation to the corporation's content standards on factual correctness, which corresponds to regulation 2.2 of the regulator's media standards.
"We have apologised for this and we agree with the authority's determination in full. We will adhere to the sanction as soon as the date and language are finalised."
