The British broadcaster engaged in a "serious breach" of industry standards by failing to disclose that the presenter of a documentary about the Gaza situation was the child of a Hamas official, as determined by British broadcasting authority Ofcom.
An probe by the media regulator into Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The head of the BBC had earlier expressed regret, stating there had been "a significant failing in relation to factual correctness".
The authority has ordered the BBC to transmit a evening statement about its conclusions.
"As this represents a serious breach of our regulations, we are directing the BBC to air a announcement of our determinations against it on BBC Two at 21:00, with a date to be finalised," the statement read.
'Risk to Erode Confidence'
The watchdog's announcement declared: "The inquiry we conducted found that the programme's lack of disclosure that the voice's male guardian held a role in the Hamas-controlled authority was substantially inaccurate.
"It meant that the audience did not have critical information which may have been extremely pertinent to their assessment of the voice and the content he provided.
"Credibility is at the heart of the relationship between a media organization and its audience, especially for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the possibility to undermine the exceptionally strong levels of confidence that audiences would have invested in a factual film from the broadcaster about the Gaza conflict."
The documentary was withdrawn from the BBC's streaming service in the month of February after the boy's family links were revealed, and in the month of July an broadcaster's internal assessment concluded it violated the corporation's editorial guidelines on accuracy.
A representative for the broadcaster commented: "The regulator's decision is in line with the conclusions of the internal assessment, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on accuracy, which aligns with clause 2.2 of the regulator's media standards.
"We expressed regret for this and we accept the regulator's ruling in full. We will adhere to the directive as soon as the schedule and language are confirmed."
