The public service broadcaster committed a "serious breach" of broadcasting rules by not revealing that the narrator of a documentary about the Gaza situation was the son of a Hamas representative, as determined by regulatory body Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The head of the BBC had previously apologised, noting there had been "a major oversight in relation to truthfulness".
The authority has ordered the broadcaster to air a prime-time announcement about its decisions.
"Given this constitutes a major infringement of our rules, we are instructing the BBC to transmit a message of our findings against it on the BBC's second channel at 9pm, with a timing to be finalised," the regulator stated.
'Possibility to Undermine Confidence'
The watchdog's announcement said: "Our probe found that the programme's lack of disclosure that the voice's male guardian served in a post in the Hamas-administered administration was substantially inaccurate.
"Consequently that the audience did not have vital facts which may have been highly relevant to their judgment of the presenter and the information he presented.
"Confidence is at the center of the connection between a television network and its viewers, especially for a national broadcasting corporation such as the BBC.
"This oversight had the possibility to erode the exceptionally strong degrees of credibility that the public would have put in a factual film from the broadcaster about the Israel-Gaza war."
The film was removed from the online platform in February after the presenter's personal associations were revealed, and in this past July an broadcaster's internal assessment concluded it breached the corporation's editorial guidelines on accuracy.
A corporation official said: "The regulator's decision is in accordance with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which aligns with Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with Ofcom's decision in full. We will adhere to the directive as soon as the date and wording are confirmed."
