The public service broadcaster engaged in a "major breach" of broadcasting rules by failing to disclose that the presenter of a programme about Gaza was the son of a Hamas administrator, according to UK media regulator Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The head of the BBC had earlier expressed regret, noting there had been "a serious error in relation to accuracy".
The regulator has ordered the corporation to transmit a evening statement about its decisions.
"As this represents a serious breach of our regulations, we are directing the broadcaster to air a announcement of our determinations against it on BBC2 at nine o'clock in the evening, with a schedule to be confirmed," the regulator stated.
'Potential to Damage Confidence'
The authority's announcement said: "The inquiry we conducted determined that the documentary's failure to disclose that the presenter's father served in a position in the Hamas-controlled authority was significantly deceptive.
"It meant that the audience did not have essential details which may have been highly relevant to their evaluation of the narrator and the content he shared.
"Credibility is at the heart of the bond between a media organization and its audience, notably for a public service broadcaster such as the BBC.
"This failing had the possibility to undermine the very considerable levels of confidence that audiences would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was withdrawn from the online platform in last February after the narrator's personal associations emerged, and in the month of July an corporation's own inquiry determined it infringed the broadcaster's journalistic standards on factual correctness.
A corporation official commented: "The authority's determination is in agreement with the results of the corporation's inquiry, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on truthfulness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept Ofcom's decision in its entirety. We will adhere to the directive as soon as the schedule and wording are finalised."
