The public service broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the voice of a documentary about the Gaza situation was the child of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The BBC's director general had earlier expressed regret, saying there had been "a significant failing in relation to accuracy".
The authority has instructed the BBC to transmit a evening statement about its findings.
"Given this constitutes a major infringement of our rules, we are directing the broadcaster to air a statement of our conclusions against it on BBC2 at 9pm, with a schedule to be confirmed," the statement read.
'Potential to Erode Confidence'
The regulator's report declared: "Our investigation determined that the programme's failure to disclose that the narrator's father held a role in the Hamas-administered administration was substantially inaccurate.
"Consequently that the audience did not have essential details which may have been extremely pertinent to their judgment of the voice and the information he shared.
"Confidence is at the heart of the bond between a television network and its viewers, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the risk to erode the significantly high amounts of credibility that viewers would have invested in a BBC factual programme about the conflict in Gaza."
The film was removed from the BBC's streaming service in last February after the boy's family links came to light, and in the month of July an broadcaster's internal assessment concluded it infringed the organization's content policies on factual correctness.
A corporation official stated: "The authority's determination is in accordance with the findings of the internal assessment, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on truthfulness, which corresponds to Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we accept Ofcom's decision in its entirety. We will follow the sanction as soon as the timing and wording are finalised."
