The British broadcaster engaged in a "significant breach" of broadcasting rules by omitting to mention that the narrator of a documentary about the Gaza situation was the son of a Hamas official, according to UK media regulator Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has found that the documentary was "substantially inaccurate".
The BBC's director general had previously apologised, stating there had been "a serious error in relation to factual correctness".
The regulator has instructed the corporation to air a evening declaration about its conclusions.
"Given this constitutes a major infringement of our code, we are ordering the broadcaster to air a message of our findings against it on BBC Two at 9pm, with a date to be finalised," the statement read.
'Risk to Undermine Trust'
The authority's announcement stated: "Our investigation found that the documentary's failure to disclose that the presenter's father served in a position in the Hamas-run government was substantially inaccurate.
"This implied that the audience did not have critical information which may have been highly relevant to their evaluation of the narrator and the details he presented.
"Credibility is at the core of the connection between a broadcaster and its viewers, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the possibility to damage the very considerable amounts of trust that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The film was withdrawn from the online platform in February after the boy's family links were revealed, and in the month of July an internal BBC review concluded it violated the organization's journalistic standards on accuracy.
A representative for the broadcaster said: "The authority's determination is in accordance with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the regulator's ruling in its entirety. We will adhere to the directive as soon as the date and language are determined."
