The British broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the presenter of a film about the Gaza situation was the son of a Hamas official, as determined by British broadcasting authority Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a significant failing in relation to accuracy".
The regulator has ordered the broadcaster to broadcast a peak-time statement about its findings.
"As this represents a serious breach of our regulations, we are ordering the BBC to transmit a message of our conclusions against it on the BBC's second channel at 21:00, with a date to be finalised," the regulator stated.
'Possibility to Erode Confidence'
The authority's report stated: "The inquiry we conducted found that the programme's lack of disclosure that the presenter's parent held a post in the Hamas-controlled government was materially misleading.
"This implied that the audience did not have critical information which may have been extremely pertinent to their assessment of the narrator and the information he shared.
"Credibility is at the heart of the connection between a television network and its viewers, particularly for a national broadcasting corporation such as the BBC.
"This oversight had the possibility to damage the very considerable degrees of trust that the public would have invested in a documentary produced by the BBC about the Israel-Gaza war."
The film was removed from iPlayer in last February after the boy's personal associations were revealed, and in July an corporation's own inquiry concluded it breached the broadcaster's editorial guidelines on factual correctness.
A representative for the broadcaster stated: "The Ofcom ruling is in accordance with the results of the corporation's inquiry, that there was a significant failing in the documentary in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we agree with Ofcom's decision in its entirety. We will follow the directive as soon as the date and wording are confirmed."
