The British broadcaster was found to have committed a "serious breach" of broadcasting rules by not revealing that the narrator of a documentary about Gaza was the child of a Hamas representative, as determined by British broadcasting authority Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The head of the BBC had already issued an apology, noting there had been "a significant failing in relation to factual correctness".
The regulator has ordered the BBC to transmit a prime-time statement about its conclusions.
"Given this constitutes a serious breach of our code, we are ordering the corporation to transmit a message of our findings against it on BBC Two at nine o'clock in the evening, with a timing to be determined," the regulator stated.
'Possibility to Damage Confidence'
The authority's statement said: "The inquiry we conducted found that the film's lack of disclosure that the presenter's male guardian held a role in the Hamas-run administration was significantly deceptive.
"Consequently that the audience did not have critical information which may have been extremely pertinent to their evaluation of the presenter and the content he provided.
"Credibility is at the core of the relationship between a broadcaster and its viewers, especially for a national broadcasting corporation such as the public broadcaster.
"This oversight had the potential to undermine the significantly high amounts of credibility that the public would have put in a factual film from the broadcaster about the Gaza conflict."
The programme was removed from iPlayer in last February after the narrator's family links came to light, and in this past July an broadcaster's internal assessment determined it infringed the organization's content policies on accuracy.
A corporation official commented: "The Ofcom ruling is in accordance with the results of the internal assessment, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on accuracy, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the regulator's ruling in full. We will follow the penalty as soon as the timing and wording are finalised."
