The British broadcaster committed a "significant breach" of media regulations by omitting to mention that the presenter of a film about Gaza was the child of a Hamas administrator, as determined by regulatory body Ofcom.
An inquiry by the media regulator into 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 serious error in relation to accuracy".
The regulator has instructed the BBC to transmit a peak-time statement about its decisions.
"As this represents a significant violation of our regulations, we are instructing the BBC to broadcast a message of our conclusions against it on the BBC's second channel at 9pm, with a timing to be determined," it said.
'Risk to Damage Trust'
The watchdog's statement declared: "The inquiry we conducted concluded that the film's failure to disclose that the voice's male guardian served in a role in the Hamas-run authority was materially misleading.
"This implied that the viewers did not have essential details which may have been extremely pertinent to their evaluation of the narrator and the content he shared.
"Credibility is at the center of the connection between a media organization and its viewers, especially for a public service broadcaster such as the BBC.
"This oversight had the potential to damage the very considerable amounts of trust that viewers would have placed in a documentary produced by the BBC about the conflict in Gaza."
The documentary was withdrawn from iPlayer in the month of February after the boy's personal associations were revealed, and in this past July an broadcaster's internal assessment concluded it violated the organization's editorial guidelines on factual correctness.
A representative for the broadcaster stated: "The Ofcom ruling is in line with the conclusions of Peter Johnston's review, that there was a serious error in the film in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept Ofcom's decision in complete. We will adhere to the sanction as soon as the timing and language are confirmed."
