The public service broadcaster engaged in a "serious breach" of broadcasting rules by not revealing that the presenter of a film about the Gaza conflict was the child of a Hamas official, as determined by British broadcasting authority Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, saying there had been "a significant failing in relation to factual correctness".
The regulator has instructed the corporation to transmit a peak-time statement about its decisions.
"Since this amounts to a serious breach of our code, we are ordering the broadcaster to broadcast a statement of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be determined," it said.
'Potential to Erode Confidence'
The authority's announcement said: "Our investigation concluded that the film's omission to reveal that the presenter's parent held a role in the Hamas-run administration was significantly deceptive.
"Consequently that the audience did not have vital facts which may have been extremely pertinent to their judgment of the narrator and the content he provided.
"Trust is at the center of the bond between a media organization and its viewers, especially for a national broadcasting corporation such as the BBC.
"This error had the possibility to damage the significantly high levels of credibility that viewers would have put in a documentary produced by the BBC about the conflict in Gaza."
The film was removed from the online platform in last February after the presenter's personal associations were revealed, and in the month of July an broadcaster's internal assessment determined it infringed the organization's journalistic standards on accuracy.
A corporation official said: "The authority's determination is in agreement with the findings of the corporation's inquiry, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the authority's determination in its entirety. We will follow the directive as soon as the timing and wording are finalised."
