The British broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the narrator of a programme about Gaza was the son of a Hamas representative, according to British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, noting there had been "a major oversight in relation to factual correctness".
The authority has directed the broadcaster to broadcast a peak-time announcement about its decisions.
"As this represents a serious breach of our code, we are directing the BBC to broadcast a statement of our determinations against it on BBC2 at 21:00, with a timing to be determined," the statement read.
'Potential to Damage Credibility'
The watchdog's statement said: "Our probe found that the documentary's omission to reveal that the narrator's father served in a position in the Hamas-administered administration was substantially inaccurate.
"This implied that the public did not have essential details which may have been extremely pertinent to their assessment of the presenter and the details he provided.
"Trust is at the core of the relationship between a television network and its public, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This failing had the risk to undermine the very considerable levels of confidence that audiences would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The programme was withdrawn from the BBC's streaming service in last February after the presenter's familial connections emerged, and in this past July an corporation's own inquiry concluded it violated the corporation's content policies on truthfulness.
A BBC spokesperson commented: "The regulator's decision is in accordance with the conclusions of the corporation's inquiry, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on accuracy, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the regulator's ruling in its entirety. We will adhere to the directive as soon as the date and wording are confirmed."
