The British broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the voice of a documentary about Gaza was the child of a Hamas administrator, according to regulatory body Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The BBC's director general had previously apologised, noting there had been "a major oversight in relation to factual correctness".
The authority has directed the BBC to broadcast a prime-time statement about its decisions.
"As this represents a significant violation of our rules, we are directing the BBC to transmit a message of our determinations against it on BBC2 at 21:00, with a schedule to be determined," the regulator stated.
'Potential to Erode Confidence'
The authority's statement stated: "Our probe determined that the film's omission to reveal that the voice's parent occupied a role in the Hamas-controlled authority was materially misleading.
"Consequently that the public did not have vital facts which may have been very significant to their assessment of the presenter and the details he presented.
"Confidence is at the heart of the bond between a broadcaster and its audience, notably for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the risk to damage the exceptionally strong degrees of confidence that audiences would have put in a documentary produced by the BBC about the conflict in Gaza."
The film was removed from the BBC's streaming service in the month of February after the presenter's familial connections came to light, and in the month of July an internal BBC review found it infringed the broadcaster's content policies on truthfulness.
A representative for the broadcaster stated: "The Ofcom ruling is in agreement with the results of the corporation's inquiry, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on factual correctness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with the regulator's ruling in complete. We will comply with the directive as soon as the schedule and language are determined."
