The British broadcaster engaged in a "serious breach" of media regulations by omitting to mention that the presenter of a documentary about Gaza was the son of a Hamas administrator, as ruled by regulatory body Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The head of the BBC had already issued an apology, stating there had been "a significant failing in relation to accuracy".
The regulator has ordered the broadcaster to air a prime-time statement about its findings.
"As this represents a major infringement of our code, we are ordering the BBC to broadcast a statement of our findings against it on BBC Two at nine o'clock in the evening, with a timing to be confirmed," the regulator stated.
'Potential to Undermine Credibility'
The watchdog's statement said: "Our investigation determined that the programme's lack of disclosure that the narrator's male guardian served in a position in the Hamas-administered authority was materially misleading.
"This implied that the audience did not have vital facts which may have been very significant to their judgment of the presenter and the details he provided.
"Credibility is at the center of the connection between a broadcaster and its audience, particularly for a state-funded media outlet such as the BBC.
"This error had the risk to damage the very considerable degrees of trust that viewers would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was removed from iPlayer in February after the boy's familial connections came to light, and in this past July an internal BBC review determined it violated the corporation's editorial guidelines on factual correctness.
A representative for the broadcaster commented: "The Ofcom ruling is in accordance with the results 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 Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with the regulator's ruling in complete. We will adhere to the directive as soon as the schedule and language are finalised."
