The British broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the presenter of a documentary about the Gaza conflict was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An inquiry by Ofcom into Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to truthfulness".
The authority has ordered the corporation to transmit a prime-time statement about its conclusions.
"Given this constitutes a major infringement of our rules, we are ordering the broadcaster to broadcast a statement of our findings against it on BBC2 at nine o'clock in the evening, with a date to be finalised," the regulator stated.
'Risk to Erode Confidence'
The regulator's report declared: "Our investigation found that the documentary's omission to reveal that the voice's male guardian held a post in the Hamas-administered administration was substantially inaccurate.
"This implied that the viewers did not have critical information which may have been highly relevant to their assessment of the presenter and the details he presented.
"Trust is at the heart of the connection between a television network and its audience, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to damage the exceptionally strong amounts of trust that viewers would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The programme was removed from the online platform in last February after the narrator's personal associations emerged, and in the month of July an broadcaster's internal assessment found it breached the broadcaster's editorial guidelines on truthfulness.
A representative for the broadcaster commented: "The regulator's decision is in accordance with the conclusions of the internal assessment, that there was a serious error in the documentary in relation to the corporation's content standards on factual correctness, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the regulator's ruling in complete. We will adhere to the penalty as soon as the timing and language are finalised."
