The public service broadcaster committed a "serious breach" of media regulations by omitting to mention that the presenter of a film about the Gaza conflict was the son of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The head of the BBC had already issued an apology, noting there had been "a major oversight in relation to factual correctness".
Ofcom has ordered the broadcaster to broadcast a prime-time announcement about its findings.
"Since this amounts to a serious breach of our rules, we are instructing the BBC to air a announcement of our findings against it on BBC Two at nine o'clock in the evening, with a date to be determined," it said.
'Risk to Erode Credibility'
The regulator's report said: "Our probe concluded that the film's omission to reveal that the voice's father occupied a position in the Hamas-administered administration was materially misleading.
"This implied that the public did not have critical information which may have been very significant to their assessment of the voice and the details he shared.
"Trust is at the core of the connection between a television network and its public, particularly for a public service broadcaster such as the BBC.
"This error had the risk to damage the exceptionally strong levels of trust that viewers would have placed in a BBC factual programme about the conflict in Gaza."
The film was pulled from the BBC's streaming service in the month of February after the narrator's family links emerged, and in the month of July an corporation's own inquiry determined it breached the organization's content policies on factual correctness.
A BBC spokesperson stated: "The authority's determination is in accordance with the results of the corporation's inquiry, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the authority's determination in full. We will adhere to the directive as soon as the date and language are finalised."
