The public service broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the narrator of a film about the Gaza situation was the child of a Hamas official, as ruled by British broadcasting authority Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to accuracy".
The regulator has directed the corporation to broadcast a prime-time announcement about its conclusions.
"Since this amounts to a serious breach of our regulations, we are instructing the BBC to broadcast a statement of our determinations against it on BBC2 at 21:00, with a date to be finalised," the regulator stated.
'Potential to Erode Credibility'
The authority's announcement said: "Our probe concluded that the programme's lack of disclosure that the presenter's father occupied a position in the Hamas-controlled authority was substantially inaccurate.
"It meant that the public did not have essential details which may have been highly relevant to their assessment of the voice and the information he provided.
"Trust is at the center of the bond between a television network and its viewers, especially for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the very considerable levels of credibility that viewers would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The programme was withdrawn from iPlayer in last February after the boy's family links came to light, and in July an corporation's own inquiry concluded it breached the corporation's journalistic standards on factual correctness.
A BBC spokesperson commented: "The authority's determination is in line with the results of Peter Johnston's review, that there was a serious error in the documentary in relation to the corporation's content standards on accuracy, which aligns with Rule 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 penalty as soon as the date and language are confirmed."
