The British broadcaster was found to have committed a "serious breach" of industry standards by not revealing that the presenter of a film about Gaza was the son of a Hamas representative, as ruled by regulatory body Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has concluded that the documentary was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a significant failing in relation to accuracy".
Ofcom has ordered the corporation to transmit a prime-time announcement about its conclusions.
"Given this constitutes a major infringement of our code, we are ordering the BBC to transmit a statement of our findings against it on the BBC's second channel at nine o'clock in the evening, with a timing to be determined," the regulator stated.
'Potential to Undermine Trust'
The authority's announcement declared: "Our probe determined that the programme's omission to reveal that the voice's parent occupied a position in the Hamas-run government was significantly deceptive.
"This implied that the audience did not have vital facts which may have been highly relevant to their evaluation of the narrator and the details he shared.
"Trust is at the core of the connection between a television network and its audience, particularly for a state-funded media outlet such as the public broadcaster.
"This oversight had the potential to erode the significantly high levels of confidence that audiences would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The programme was withdrawn from iPlayer in February after the presenter's familial connections were revealed, and in the month of July an broadcaster's internal assessment found it violated the corporation's journalistic standards on truthfulness.
A representative for the broadcaster commented: "The authority's determination is in line with the findings of the internal assessment, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with the authority's determination in its entirety. We will follow the directive as soon as the date and wording are finalised."
