The British broadcaster engaged in a "significant breach" of media regulations by omitting to mention that the narrator of a film about the Gaza situation was the child of a Hamas administrator, as determined by regulatory body Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The BBC's director general had previously apologised, saying there had been "a serious error in relation to accuracy".
The authority has directed the broadcaster to air a evening statement about its findings.
"Since this amounts to a serious breach of our rules, we are directing the corporation to air a message of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a date to be finalised," the regulator stated.
'Possibility to Erode Confidence'
The regulator's announcement stated: "Our probe determined that the film's failure to disclose that the voice's parent occupied a post in the Hamas-controlled authority was materially misleading.
"This implied that the audience did not have vital facts which may have been very significant to their assessment of the voice and the content he shared.
"Trust is at the core of the relationship between a broadcaster and its public, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the possibility to erode the very considerable amounts of confidence that viewers would have put in a factual film from the broadcaster about the Israel-Gaza war."
The programme was withdrawn from the online platform in the month of February after the presenter's familial connections came to light, and in the month of July an internal BBC review found it breached the organization's journalistic standards on truthfulness.
A BBC spokesperson stated: "The regulator's decision is in agreement with the findings of Peter Johnston's review, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we comply with the authority's determination in its entirety. We will adhere to the directive as soon as the date and wording are determined."
