The public service broadcaster was found to have committed a "serious breach" of media regulations by omitting to mention that the narrator of a film about the Gaza situation was the child of a Hamas representative, as ruled by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, stating there had been "a major oversight in relation to truthfulness".
Ofcom has directed the BBC to air a evening statement about its conclusions.
"As this represents a serious breach of our regulations, we are directing the BBC to broadcast a message of our determinations against it on the BBC's second channel at 21:00, with a schedule to be confirmed," the regulator stated.
'Potential to Damage Trust'
The regulator's announcement stated: "Our probe determined that the programme's lack of disclosure that the voice's father occupied a position in the Hamas-run administration was substantially inaccurate.
"Consequently that the viewers did not have vital facts which may have been very significant to their evaluation of the narrator and the details he provided.
"Trust is at the core of the connection between a broadcaster and its viewers, particularly for a national broadcasting corporation such as the BBC.
"This oversight had the potential to damage the significantly high degrees of credibility that viewers would have invested in a documentary produced by the BBC about the Gaza conflict."
The programme was pulled from iPlayer in February after the presenter's family links were revealed, and in July an internal BBC review found it infringed the broadcaster's journalistic standards on accuracy.
A BBC spokesperson said: "The Ofcom ruling is in line 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 factual correctness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the authority's determination in full. We will adhere to the directive as soon as the date and language are confirmed."
