The British broadcaster engaged in a "major breach" of broadcasting rules by omitting to mention that the narrator of a documentary about the Gaza situation was the child of a Hamas official, according to British broadcasting authority Ofcom.
An inquiry by the media regulator into Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The head of the BBC had earlier expressed regret, saying there had been "a major oversight in relation to factual correctness".
The regulator has ordered the broadcaster to transmit a evening announcement about its conclusions.
"Since this amounts to a serious breach of our code, we are directing the BBC to broadcast a statement of our determinations against it on BBC Two at nine o'clock in the evening, with a timing to be finalised," the regulator stated.
'Potential to Undermine Confidence'
The regulator's announcement said: "Our investigation found that the documentary's lack of disclosure that the narrator's parent held a role in the Hamas-controlled administration was materially misleading.
"This implied that the audience did not have critical information which may have been highly relevant to their evaluation of the narrator and the content he shared.
"Confidence is at the center of the connection between a media organization and its public, particularly for a state-funded media outlet such as the public broadcaster.
"This oversight had the risk to damage the exceptionally strong degrees of trust that the public would have put in a factual film from the broadcaster about the Gaza conflict."
The documentary was pulled from iPlayer in last February after the boy's family links came to light, and in the month of July an internal BBC review determined it violated the organization's journalistic standards on accuracy.
A representative for the broadcaster stated: "The authority's determination is in accordance with the findings of the internal assessment, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which aligns with regulation 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the regulator's ruling in full. We will follow the directive as soon as the timing and wording are determined."
