The public service broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the narrator of a film about the Gaza situation was the son of a Hamas representative, as ruled by UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, noting there had been "a serious error in relation to truthfulness".
Ofcom has directed the broadcaster to air a prime-time statement about its findings.
"Since this amounts to a significant violation of our rules, we are ordering the corporation to broadcast a statement of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be finalised," the statement read.
'Potential to Erode Credibility'
The regulator's statement stated: "Our probe determined that the documentary's failure to disclose that the voice's male guardian served in a role in the Hamas-run administration was materially misleading.
"It meant that the public did not have essential details which may have been very significant to their assessment of the voice and the information he provided.
"Confidence is at the core of the relationship between a broadcaster and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the potential to erode the significantly high levels of credibility that audiences would have placed in a documentary produced by the BBC about the Gaza conflict."
The film was withdrawn from the online platform in last February after the narrator's familial connections came to light, and in the month of July an broadcaster's internal assessment concluded it breached the organization's content policies on factual correctness.
A BBC spokesperson stated: "The Ofcom ruling is in accordance with the findings of Peter Johnston's review, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on accuracy, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we accept Ofcom's decision in complete. We will comply with the directive as soon as the schedule and wording are finalised."
