The public service broadcaster engaged in a "major breach" of media regulations by not revealing that the presenter of a documentary about the Gaza situation was the son of a Hamas administrator, as ruled by UK media regulator Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The BBC's director general had earlier expressed regret, stating there had been "a major oversight in relation to accuracy".
The authority has directed the corporation to air a prime-time statement about its decisions.
"Given this constitutes a major infringement of our regulations, we are ordering the corporation to transmit a statement of our findings against it on BBC Two at nine o'clock in the evening, with a date to be determined," it said.
'Risk to Damage Trust'
The authority's report stated: "The inquiry we conducted determined that the programme's failure to disclose that the voice's father served in a role in the Hamas-administered administration was significantly deceptive.
"Consequently that the audience did not have vital facts which may have been extremely pertinent to their assessment of the voice and the content he shared.
"Confidence is at the center of the connection between a media organization and its audience, particularly for a public service broadcaster such as the BBC.
"This failing had the potential to erode the significantly high degrees of credibility that the public would have put in a BBC factual programme 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 found it violated the broadcaster's journalistic standards on accuracy.
A representative for the broadcaster stated: "The Ofcom ruling is in agreement with the findings of the corporation's inquiry, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on factual correctness, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept Ofcom's decision in its entirety. We will follow the sanction as soon as the schedule and wording are finalised."
