The public service broadcaster engaged in a "significant breach" of industry standards by omitting to mention that the presenter of a film about the Gaza conflict was the child of a Hamas representative, according to UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The BBC's director general had already issued an apology, stating there had been "a serious error in relation to factual correctness".
The regulator has instructed the corporation to air a prime-time declaration about its conclusions.
"As this represents a significant violation of our code, 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 determined," the statement read.
'Potential to Erode Confidence'
The watchdog's announcement stated: "Our investigation concluded that the film's lack of disclosure that the narrator's father served in a role in the Hamas-run administration was substantially inaccurate.
"It meant that the public did not have vital facts which may have been highly relevant to their evaluation of the voice and the content he shared.
"Confidence is at the heart of the relationship between a broadcaster and its audience, especially for a public service broadcaster such as the BBC.
"This failing had the potential to undermine the very considerable degrees of trust that audiences would have placed in a BBC factual programme about the Israel-Gaza war."
The programme was removed from the online platform in February after the narrator's family links emerged, and in the month of July an internal BBC review determined it infringed the organization's journalistic standards on factual correctness.
A representative for the broadcaster commented: "The Ofcom ruling is in accordance with the conclusions of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on truthfulness, which aligns with regulation 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with Ofcom's decision in complete. We will adhere to the directive as soon as the date and wording are confirmed."
