The British broadcaster committed a "major breach" of broadcasting rules by omitting to mention that the narrator of a documentary about Gaza was the son of a Hamas representative, as ruled by UK media regulator Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The BBC's director general had previously apologised, saying there had been "a serious error in relation to accuracy".
The regulator has directed the corporation to broadcast a prime-time statement about its conclusions.
"As this represents a major infringement of our rules, we are ordering the broadcaster to broadcast a statement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a timing to be finalised," the statement read.
'Risk to Undermine Trust'
The regulator's announcement stated: "The inquiry we conducted found that the film's omission to reveal that the voice's male guardian occupied a position in the Hamas-administered government was materially misleading.
"This implied that the viewers did not have vital facts which may have been extremely pertinent to their evaluation of the narrator and the content he shared.
"Confidence is at the core of the relationship between a broadcaster and its public, notably for a national broadcasting corporation such as the public broadcaster.
"This oversight had the potential to erode the exceptionally strong levels of confidence that viewers would have invested in a documentary produced by the BBC about the Gaza conflict."
The documentary was removed from the online platform in the month of February after the narrator's personal associations came to light, and in this past July an broadcaster's internal assessment determined it infringed the organization's content policies on truthfulness.
A representative for the broadcaster commented: "The authority's determination is in accordance with the conclusions of Peter Johnston's review, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the authority's determination in complete. We will follow the sanction as soon as the date and wording are determined."
