The British broadcaster engaged in a "significant breach" of industry standards by omitting to mention that the narrator of a film about the Gaza situation was the offspring of a Hamas official, as determined by regulatory body 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 earlier expressed regret, saying there had been "a major oversight in relation to factual correctness".
The regulator has instructed the BBC to transmit a prime-time statement about its conclusions.
"Since this amounts to a major infringement of our code, we are instructing the corporation to transmit a message of our conclusions against it on BBC2 at nine o'clock in the evening, with a timing to be finalised," the statement read.
'Potential to Undermine Confidence'
The watchdog's report said: "Our investigation determined that the film's lack of disclosure that the presenter's parent served in a post in the Hamas-run authority was significantly deceptive.
"This implied that the audience did not have critical information which may have been highly relevant to their judgment of the voice and the content he shared.
"Credibility is at the center of the connection between a broadcaster and its viewers, particularly for a public service broadcaster such as the public broadcaster.
"This failing had the potential to erode the very considerable amounts of trust that viewers would have placed in a factual film from the broadcaster about the conflict in Gaza."
The film was removed from the BBC's streaming service in the month of February after the boy's personal associations emerged, and in the month of July an corporation's own inquiry concluded it breached the corporation's journalistic standards on truthfulness.
A BBC spokesperson commented: "The regulator's decision is in agreement with the findings of the corporation's inquiry, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with the regulator's ruling in its entirety. We will follow the directive as soon as the timing and wording are confirmed."
