The public service broadcaster was found to have committed a "major breach" of media regulations by not revealing that the narrator of a film about the Gaza conflict was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The chief executive of the broadcaster had already issued an apology, noting there had been "a significant failing in relation to factual correctness".
Ofcom has instructed the BBC to broadcast a peak-time declaration about its conclusions.
"Given this constitutes a significant violation of our rules, we are instructing the broadcaster to air a statement of our determinations against it on BBC Two at 21:00, with a date to be determined," it said.
'Potential to Undermine Credibility'
The watchdog's announcement stated: "The inquiry we conducted concluded that the film's omission to reveal that the voice's father served in a post in the Hamas-administered administration was significantly deceptive.
"This implied that the viewers did not have vital facts which may have been highly relevant to their assessment of the narrator and the information he presented.
"Confidence is at the center of the connection between a broadcaster and its public, notably for a public service broadcaster such as the BBC.
"This oversight had the risk to undermine the significantly high degrees of credibility that viewers would have put in a BBC factual programme about the Israel-Gaza war."
The film was pulled from the online platform in last February after the narrator's familial connections emerged, and in the month of July an internal BBC review determined it infringed the corporation's editorial guidelines on factual correctness.
A representative for the broadcaster commented: "The Ofcom ruling is in line with the results of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in complete. We will adhere to the directive as soon as the timing and wording are determined."
