The British broadcaster was found to have committed a "serious breach" of media regulations by omitting to mention that the narrator of a programme about the Gaza situation was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The head of the BBC had earlier expressed regret, stating there had been "a serious error in relation to factual correctness".
The authority has ordered the broadcaster to air a peak-time declaration about its conclusions.
"Since this amounts to a major infringement of our regulations, we are instructing the broadcaster to air a announcement of our conclusions against it on the BBC's second channel at 21:00, with a date to be determined," the statement read.
'Risk to Damage Credibility'
The regulator's announcement declared: "The inquiry we conducted determined that the programme's lack of disclosure that the presenter's parent served in a post in the Hamas-controlled administration was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been very significant to their judgment of the voice and the details he presented.
"Credibility is at the center of the connection between a media organization and its public, especially for a public service broadcaster such as the public broadcaster.
"This error had the possibility to erode the very considerable levels of confidence that audiences would have invested in a BBC factual programme about the Israel-Gaza war."
The documentary was pulled from the BBC's streaming service in February after the boy's personal associations emerged, and in the month of July an corporation's own inquiry concluded it breached the corporation's journalistic standards on factual correctness.
A corporation official commented: "The Ofcom ruling is in agreement with the results of the internal assessment, that there was a major oversight in the documentary in relation to the corporation's content standards on truthfulness, which corresponds to regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in complete. We will adhere to the directive as soon as the date and language are confirmed."
