The British broadcaster committed a "significant breach" of industry standards by not revealing that the presenter of a film about the Gaza situation was the child of a Hamas official, as determined 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 "materially misleading".
The BBC's director general had earlier expressed regret, noting there had been "a major oversight in relation to accuracy".
The regulator has ordered the corporation to air a evening announcement about its findings.
"Given this constitutes a major infringement of our code, we are directing the BBC to transmit a statement of our determinations against it on BBC Two at nine o'clock in the evening, with a schedule to be confirmed," the regulator stated.
'Risk to Undermine Credibility'
The regulator's statement stated: "The inquiry we conducted determined that the documentary's omission to reveal that the presenter's parent occupied a role in the Hamas-administered administration was significantly deceptive.
"This implied that the public did not have vital facts which may have been very significant to their evaluation of the voice and the details he shared.
"Confidence is at the core of the bond between a media organization and its audience, especially for a state-funded media outlet such as the BBC.
"This failing had the risk to erode the exceptionally strong degrees of credibility that the public would have invested in a documentary produced by the BBC about the Gaza conflict."
The documentary was withdrawn from iPlayer in the month of February after the narrator's familial connections were revealed, and in the month of July an broadcaster's internal assessment found it infringed the organization's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The Ofcom ruling is in line with the results of Peter Johnston's review, that there was a major oversight in the film in relation to the corporation's content standards on accuracy, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the regulator's ruling in complete. We will adhere to the directive as soon as the date and wording are finalised."
