The British broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the narrator of a film about the Gaza situation was the offspring of a Hamas official, as determined by UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The BBC's director general had previously apologised, stating there had been "a serious error in relation to factual correctness".
The regulator has directed the broadcaster to broadcast a peak-time declaration about its conclusions.
"Since this amounts to a significant violation of our rules, we are ordering the BBC to transmit a announcement of our determinations against it on BBC2 at 9pm, with a date to be finalised," it said.
'Possibility to Damage Confidence'
The regulator's statement said: "Our probe determined that the documentary's lack of disclosure that the presenter's father occupied a post in the Hamas-run government was substantially inaccurate.
"It meant that the public did not have essential details which may have been extremely pertinent to their judgment of the presenter and the information he provided.
"Credibility is at the center of the bond between a broadcaster and its public, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the potential to erode the significantly high amounts of credibility that the public would have invested in a documentary produced by the BBC about the Israel-Gaza war."
The documentary was withdrawn from the BBC's streaming service in the month of February after the presenter's family links emerged, and in the month of July an internal BBC review found it breached the corporation's journalistic standards on factual correctness.
A corporation official said: "The authority's determination is in accordance with the findings of the corporation's inquiry, that there was a significant failing in the documentary in relation to the BBC's Editorial Guidelines on accuracy, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with the authority's determination in its entirety. We will follow the directive as soon as the schedule and wording are confirmed."
