The British broadcaster committed a "significant breach" of media regulations by omitting to mention that the presenter of a programme about the Gaza conflict was the child of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The head of the BBC had already issued an apology, noting there had been "a serious error in relation to factual correctness".
The authority has directed the corporation to broadcast a evening statement about its decisions.
"Given this constitutes a significant violation of our code, we are ordering the corporation to broadcast a announcement of our findings against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be determined," the statement read.
'Risk to Undermine Confidence'
The regulator's statement declared: "The inquiry we conducted concluded that the documentary's lack of disclosure that the voice's father served in a post in the Hamas-controlled administration was materially misleading.
"This implied that the audience did not have vital facts which may have been highly relevant to their evaluation of the narrator and the information he shared.
"Credibility is at the center of the bond between a television network and its public, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the potential to damage the exceptionally strong amounts of confidence that viewers would have placed in a BBC factual programme about the conflict in Gaza."
The film was removed from the BBC's streaming service in the month of February after the boy's familial connections emerged, and in this past July an internal BBC review found it violated the organization's journalistic standards on accuracy.
A representative for the broadcaster said: "The regulator's decision is in accordance with the conclusions of the corporation's inquiry, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will adhere to the directive as soon as the timing and wording are determined."
