The British broadcaster engaged in a "significant breach" of broadcasting rules by not revealing that the presenter of a documentary about Gaza was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to accuracy".
The regulator has instructed the BBC to broadcast a evening declaration about its conclusions.
"Given this constitutes a significant violation of our rules, we are directing the broadcaster to transmit a statement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a date to be confirmed," the statement read.
'Risk to Undermine Trust'
The watchdog's report said: "Our probe determined that the documentary's lack of disclosure that the narrator's parent occupied a post in the Hamas-run government was significantly deceptive.
"It meant that the public did not have essential details which may have been extremely pertinent to their assessment of the presenter and the content he shared.
"Credibility is at the core of the bond between a broadcaster and its viewers, especially for a public service broadcaster such as the BBC.
"This error had the risk to damage the exceptionally strong degrees of credibility that the public would have placed in a BBC factual programme about the Israel-Gaza war."
The film was pulled from iPlayer in last February after the boy's familial connections emerged, and in the month of July an broadcaster's internal assessment found it infringed the corporation's journalistic standards on factual correctness.
A corporation official said: "The regulator's decision is in accordance with the conclusions of the internal assessment, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on truthfulness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the authority's determination in full. We will follow the penalty as soon as the timing and language are determined."
