The BBC committed a "serious breach" of broadcasting rules by omitting to mention that the narrator of a programme about the Gaza conflict was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to factual correctness".
Ofcom has ordered the broadcaster to broadcast a peak-time statement about its findings.
"As this represents a significant violation of our rules, we are ordering the broadcaster to transmit a announcement of our determinations against it on BBC Two at nine o'clock in the evening, with a timing to be finalised," the statement read.
'Potential to Erode Credibility'
The authority's report declared: "Our probe determined that the documentary's omission to reveal that the narrator's parent served in a post in the Hamas-administered authority was materially misleading.
"Consequently that the viewers did not have essential details which may have been extremely pertinent to their judgment of the voice and the details he presented.
"Trust is at the heart of the relationship between a television network and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the risk to erode the very considerable levels of trust that the public would have invested in a BBC factual programme about the Israel-Gaza war."
The documentary was withdrawn from iPlayer in the month of February after the narrator's familial connections were revealed, and in the month of July an broadcaster's internal assessment found it breached the organization's journalistic standards on accuracy.
A corporation official commented: "The regulator's decision is in accordance with the findings of the corporation's inquiry, that there was a major oversight in the documentary in relation to the corporation's content standards on truthfulness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in its entirety. We will follow the directive as soon as the timing and language are confirmed."
