The public service broadcaster engaged in a "significant breach" of broadcasting rules by omitting to mention that the narrator of a documentary about the Gaza conflict was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An probe by the media regulator into Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has instructed the corporation to broadcast a prime-time announcement about its decisions.
"Since this amounts to a major infringement of our code, we are instructing the corporation to broadcast a announcement of our findings against it on BBC Two at 9pm, with a date to be confirmed," the statement read.
'Risk to Erode Credibility'
The regulator's report declared: "Our investigation determined that the programme's lack of disclosure that the presenter's male guardian served in a position in the Hamas-run authority was substantially inaccurate.
"Consequently that the public did not have essential details which may have been very significant to their assessment of the narrator and the information he shared.
"Trust is at the core of the connection between a media organization and its viewers, particularly for a public service broadcaster such as the public broadcaster.
"This failing had the potential to erode the significantly high levels of trust that audiences would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The programme was removed from iPlayer in the month of February after the boy's familial connections came to light, and in the month of July an corporation's own inquiry determined it breached the corporation's journalistic standards on accuracy.
A corporation official said: "The authority's determination is in accordance with the findings of the internal assessment, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with clause 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with Ofcom's decision in its entirety. We will adhere to the directive as soon as the date and wording are finalised."
