The public service broadcaster engaged in a "serious breach" of broadcasting rules by omitting to mention that the voice of a documentary about Gaza was the offspring of a Hamas administrator, according to British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The head of the BBC had previously apologised, saying there had been "a major oversight in relation to factual correctness".
The regulator has ordered the broadcaster to transmit a prime-time announcement about its conclusions.
"Given this constitutes a significant violation of our regulations, we are ordering the broadcaster to broadcast a message of our determinations against it on BBC2 at 9pm, with a timing to be determined," the statement read.
'Possibility to Undermine Trust'
The authority's report said: "The inquiry we conducted found that the programme's omission to reveal that the narrator's male guardian occupied a post in the Hamas-administered administration was substantially inaccurate.
"It meant that the audience did not have critical information which may have been highly relevant to their judgment of the voice and the content he provided.
"Confidence is at the core of the relationship between a broadcaster and its viewers, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the risk to undermine the exceptionally strong amounts of trust that viewers would have invested in a documentary produced by the BBC about the Gaza conflict."
The film was removed from the online platform in the month of February after the boy's familial connections came to light, and in July an internal BBC review concluded it violated the corporation's editorial guidelines on truthfulness.
A representative for the broadcaster stated: "The Ofcom ruling is in agreement with the results of the corporation's inquiry, that there was a major oversight in the documentary in relation to the broadcaster's journalistic policies on accuracy, which corresponds to Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with the regulator's ruling in its entirety. We will adhere to the directive as soon as the date and wording are finalised."
