The BBC was found to have committed a "major breach" of broadcasting rules by not revealing that the voice of a film about the Gaza situation was the child of a Hamas representative, as determined by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a major oversight in relation to accuracy".
Ofcom has directed the broadcaster to transmit a evening announcement about its findings.
"Since this amounts to a serious breach of our code, we are directing the broadcaster to broadcast a message of our determinations against it on BBC2 at nine o'clock in the evening, with a schedule to be finalised," the statement read.
'Potential to Damage Credibility'
The regulator's report stated: "Our probe concluded that the documentary's failure to disclose that the voice's parent served in a position in the Hamas-administered authority was significantly deceptive.
"It meant that the public did not have critical information which may have been very significant to their judgment of the presenter and the information he presented.
"Trust is at the center of the connection between a broadcaster and its audience, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This error had the possibility to undermine the very considerable amounts of confidence that the public would have placed in a documentary produced by the BBC about the conflict in Gaza."
The documentary was pulled from the online platform in the month of February after the boy's familial connections emerged, and in this past July an internal BBC review found it breached the organization's content policies on factual correctness.
A BBC spokesperson commented: "The regulator's decision is in agreement with the results of the internal assessment, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept the authority's determination in complete. We will adhere to the sanction as soon as the timing and wording are confirmed."
