The BBC was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the narrator of a documentary about the Gaza situation was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An inquiry by Ofcom into Gaza: How to Survive a Warzone has determined that the programme 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 corporation to broadcast a prime-time statement about its decisions.
"Given this constitutes a serious breach of our code, we are instructing the BBC to transmit a statement of our conclusions against it on the BBC's second channel at 21:00, with a date to be finalised," the statement read.
'Possibility to Undermine Confidence'
The authority's report declared: "The inquiry we conducted concluded that the film's lack of disclosure that the narrator's father served in a post in the Hamas-administered authority was substantially inaccurate.
"It meant that the public did not have critical information which may have been extremely pertinent to their assessment of the narrator and the details he shared.
"Trust is at the heart of the relationship between a media organization and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This error had the possibility to erode the exceptionally strong amounts of credibility that audiences would have placed in a BBC factual programme about the Israel-Gaza war."
The film was pulled from the online platform in the month of February after the boy's personal associations came to light, and in July an broadcaster's internal assessment concluded it violated the broadcaster's content policies on factual correctness.
A corporation official said: "The authority's determination is in agreement with the findings of Peter Johnston's review, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on factual correctness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in its entirety. We will follow the penalty as soon as the schedule and wording are confirmed."
