The British broadcaster was found to have committed a "significant breach" of industry standards by failing to disclose that the narrator of a documentary about Gaza was the child of a Hamas official, as ruled by British broadcasting authority Ofcom.
An inquiry by Ofcom into Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, noting there had been "a significant failing in relation to accuracy".
The regulator has ordered the BBC to broadcast a peak-time statement about its findings.
"Given this constitutes a serious breach of our code, we are directing the broadcaster to air a statement of our determinations against it on BBC Two at 21:00, with a timing to be confirmed," it said.
'Potential to Damage Confidence'
The watchdog's announcement stated: "Our investigation concluded that the documentary's failure to disclose that the voice's father served in a position in the Hamas-administered government was significantly deceptive.
"Consequently that the public did not have essential details which may have been very significant to their judgment of the presenter and the content he provided.
"Credibility is at the core of the connection between a broadcaster and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the possibility to damage the exceptionally strong levels of confidence that audiences would have placed in a BBC factual programme about the Gaza conflict."
The programme was withdrawn from the BBC's streaming service in the month of February after the boy's family links emerged, and in July an corporation's own inquiry determined it breached the organization's editorial guidelines on truthfulness.
A representative for the broadcaster commented: "The regulator's decision is in line with the findings of the corporation's inquiry, that there was a major oversight in the programme in relation to the corporation's content standards on accuracy, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in full. We will comply with the directive as soon as the date and wording are confirmed."
