The British broadcaster engaged in a "major breach" of media regulations by omitting to mention that the narrator of a documentary about Gaza was the son of a Hamas administrator, as determined by regulatory body Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a major oversight in relation to accuracy".
Ofcom has instructed the corporation to broadcast a peak-time announcement about its decisions.
"Given this constitutes a major infringement of our rules, we are ordering the broadcaster to air a announcement of our findings against it on the BBC's second channel at 21:00, with a schedule to be confirmed," the regulator stated.
'Risk to Damage Confidence'
The authority's statement stated: "Our probe concluded that the programme's omission to reveal that the narrator's male guardian occupied a post in the Hamas-administered authority was significantly deceptive.
"Consequently that the audience did not have critical information which may have been highly relevant to their judgment of the voice and the information he provided.
"Credibility is at the core of the bond between a broadcaster and its public, notably for a national broadcasting corporation such as the public broadcaster.
"This failing had the risk to damage the very considerable degrees of credibility that the public would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The programme was removed from iPlayer in the month of February after the presenter's personal associations emerged, and in July an broadcaster's internal assessment found it violated the broadcaster's editorial guidelines on accuracy.
A corporation official stated: "The Ofcom ruling is in line with the conclusions of Peter Johnston's review, that there was a significant failing in the programme in relation to the corporation's content standards on factual correctness, which corresponds to Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the regulator's ruling in full. We will adhere to the directive as soon as the date and wording are determined."
