The British broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the presenter of a programme about the Gaza situation was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "substantially inaccurate".
The BBC's director general had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The authority has directed the BBC to air a evening statement about its findings.
"As this represents a major infringement of our code, we are ordering the broadcaster to broadcast a announcement of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a date to be finalised," the regulator stated.
'Risk to Damage Trust'
The watchdog's report stated: "The inquiry we conducted concluded that the film's lack of disclosure that the voice's parent occupied a position in the Hamas-run administration was substantially inaccurate.
"This implied that the viewers did not have critical information which may have been very significant to their judgment of the narrator and the content he provided.
"Trust is at the center of the bond between a media organization and its public, particularly for a national broadcasting corporation such as the BBC.
"This error had the potential to damage the exceptionally strong degrees of credibility that audiences would have placed in a documentary produced by the BBC about the Gaza conflict."
The documentary was pulled from the BBC's streaming service in February after the narrator's familial connections came to light, and in the month of July an internal BBC review found it breached the corporation's content policies on truthfulness.
A representative for the broadcaster stated: "The Ofcom ruling is in line with the conclusions of Peter Johnston's review, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the regulator's ruling in complete. We will adhere to the directive as soon as the timing and wording are confirmed."
