The British broadcaster committed a "major breach" of media regulations by omitting to mention that the presenter of a film about Gaza was the offspring of a Hamas administrator, according to British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to accuracy".
Ofcom has directed the broadcaster to transmit a peak-time announcement about its findings.
"As this represents a serious breach of our rules, we are ordering the broadcaster to air a statement of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a date to be finalised," the regulator stated.
'Potential to Damage Credibility'
The regulator's statement declared: "Our probe concluded that the documentary's failure to disclose that the narrator's father occupied a position in the Hamas-controlled administration was materially misleading.
"This implied that the public did not have critical information which may have been highly relevant to their judgment of the presenter and the information he shared.
"Confidence is at the heart of the connection between a broadcaster and its public, notably for a national broadcasting corporation such as the BBC.
"This oversight had the potential to damage the significantly high levels of trust that viewers would have placed in a documentary produced by the BBC about the conflict in Gaza."
The programme was withdrawn from the BBC's streaming service in the month of February after the narrator's familial connections emerged, and in the month of July an broadcaster's internal assessment found it breached the broadcaster's journalistic standards on accuracy.
A BBC spokesperson stated: "The regulator's decision is in accordance with the findings of the internal assessment, that there was a significant failing in the programme in relation to the corporation's content standards on truthfulness, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the authority's determination in complete. We will comply with the directive as soon as the date and wording are determined."
