The public service broadcaster committed a "major breach" of broadcasting rules by omitting to mention that the narrator of a documentary about the Gaza situation was the child of a Hamas official, according to British broadcasting authority Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a major oversight in relation to factual correctness".
Ofcom has ordered the BBC to transmit a prime-time statement about its decisions.
"Given this constitutes a significant violation of our rules, we are instructing the BBC to air a statement of our determinations against it on BBC2 at 9pm, with a date to be determined," the statement read.
'Risk to Undermine Credibility'
The regulator's announcement said: "The inquiry we conducted concluded that the documentary's failure to disclose that the voice's parent served in a post in the Hamas-run administration was significantly deceptive.
"Consequently that the viewers did not have critical information which may have been very significant to their evaluation of the presenter and the content he presented.
"Credibility is at the heart of the relationship between a broadcaster and its audience, particularly for a public service broadcaster such as the BBC.
"This error had the potential to undermine the very considerable degrees of confidence that the public would have invested in a documentary produced by the BBC about the Gaza conflict."
The film was pulled from the online platform in last February after the boy's family links emerged, and in the month of July an corporation's own inquiry found it violated the organization's journalistic standards on accuracy.
A corporation official said: "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 broadcaster's journalistic policies on truthfulness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with Ofcom's decision in full. We will follow the penalty as soon as the date and language are finalised."
