The British broadcaster committed a "serious breach" of industry standards by failing to disclose that the voice of a documentary about the Gaza conflict was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The BBC's director general had already issued an apology, noting there had been "a major oversight in relation to factual correctness".
The regulator has instructed the BBC to transmit a peak-time announcement about its decisions.
"As this represents a serious breach of our code, we are directing the broadcaster to broadcast a statement of our conclusions against it on the BBC's second channel at 9pm, with a schedule to be confirmed," the regulator stated.
The regulator's announcement stated: "Our investigation concluded that the documentary's lack of disclosure that the narrator's parent served in a position in the Hamas-administered administration was significantly deceptive.
"This implied that the audience did not have vital facts which may have been very significant to their assessment of the presenter and the details he provided.
"Credibility is at the center of the bond between a media organization and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the risk to erode the significantly high degrees of confidence that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was removed from the online platform in February after the presenter's personal associations emerged, and in July an corporation's own inquiry concluded it violated the corporation's content policies on factual correctness.
A BBC spokesperson commented: "The Ofcom ruling is in agreement with the findings of Peter Johnston's review, that there was a serious error in the film in relation to the corporation's content standards on accuracy, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in full. We will follow the sanction as soon as the schedule and wording are finalised."
