The public service broadcaster was found to have committed a "significant breach" of industry standards by not revealing that the narrator of a film about Gaza was the son of a Hamas administrator, according to UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The head of the BBC had already issued an apology, noting there had been "a serious error in relation to accuracy".
Ofcom has ordered the broadcaster to broadcast a prime-time statement about its conclusions.
"Since this amounts to a serious breach of our rules, we are instructing the corporation to transmit a statement of our findings against it on BBC Two at 9pm, with a schedule to be confirmed," the regulator stated.
'Possibility to Damage Trust'
The authority's statement stated: "The inquiry we conducted found that the film's omission to reveal that the narrator's male guardian occupied a position in the Hamas-controlled government was substantially inaccurate.
"It meant that the audience did not have essential details which may have been highly relevant to their assessment of the narrator and the information he shared.
"Credibility is at the center of the connection between a broadcaster and its public, especially for a national broadcasting corporation such as the public broadcaster.
"This failing had the risk to damage the very considerable degrees of trust that audiences would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was removed from the online platform in the month of February after the boy's family links emerged, and in the month of July an broadcaster's internal assessment determined it infringed the corporation's journalistic standards on accuracy.
A corporation official stated: "The authority's determination is in accordance with the findings of the corporation's inquiry, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on accuracy, which aligns with Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with Ofcom's decision in complete. We will adhere to the directive as soon as the schedule and wording are determined."
