The British broadcaster committed a "major breach" of industry standards by not revealing that the presenter of a film about Gaza was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The BBC's director general had earlier expressed regret, stating there had been "a significant failing in relation to accuracy".
The authority has directed the corporation to transmit a peak-time announcement about its decisions.
"Given this constitutes a serious breach of our rules, we are ordering the BBC to broadcast a announcement of our determinations against it on BBC2 at nine o'clock in the evening, with a timing to be determined," it said.
'Risk to Damage Trust'
The watchdog's report declared: "The inquiry we conducted concluded that the programme's failure to disclose that the narrator's father served in a post in the Hamas-controlled authority was substantially inaccurate.
"It meant that the audience did not have critical information which may have been very significant to their evaluation of the presenter and the content he presented.
"Confidence is at the core of the relationship between a media organization and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the risk to erode the significantly high degrees of confidence that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was withdrawn from the online platform in last February after the boy's family links came to light, and in July an broadcaster's internal assessment found it infringed the organization's editorial guidelines on truthfulness.
A representative for the broadcaster commented: "The authority's determination is in line with the findings of the internal assessment, that there was a serious error in the programme in relation to the corporation's content standards on accuracy, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the authority's determination in its entirety. We will adhere to the directive as soon as the timing and language are determined."
