The BBC was found to have committed a "major breach" of media regulations by failing to disclose that the voice of a film about the Gaza situation was the offspring of a Hamas official, according to UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to factual correctness".
The regulator has instructed the broadcaster to air a evening statement about its findings.
"Since this amounts to a serious breach of our code, we are directing the corporation to air a message of our determinations against it on BBC Two at nine o'clock in the evening, with a schedule to be finalised," the statement read.
'Risk to Damage Trust'
The regulator's report said: "Our probe concluded that the documentary's omission to reveal that the voice's parent served in a position in the Hamas-administered administration was significantly deceptive.
"This implied that the audience did not have critical information which may have been very significant to their judgment of the voice and the content he provided.
"Trust is at the heart of the connection between a media organization and its viewers, notably for a national broadcasting corporation such as the BBC.
"This failing had the possibility to damage the significantly high levels of credibility that the public would have put in a documentary produced by the BBC about the Israel-Gaza war."
The programme was pulled from the BBC's streaming service in the month of February after the narrator's familial connections came to light, and in this past July an internal BBC review concluded it breached the broadcaster's editorial guidelines on factual correctness.
A representative for the broadcaster commented: "The authority's determination is in line with the conclusions of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on accuracy, which corresponds to regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will follow the sanction as soon as the timing and wording are confirmed."
