The BBC was found to have committed a "serious breach" of industry standards by failing to disclose that the narrator of a film about the Gaza conflict was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An inquiry by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the programme was "materially misleading".
The BBC's director general had previously apologised, stating there had been "a significant failing in relation to truthfulness".
The regulator has instructed the broadcaster to air a evening declaration about its decisions.
"Since this amounts to a significant violation of our code, we are instructing the corporation to air a statement of our determinations against it on BBC Two at 9pm, with a schedule to be confirmed," the regulator stated.
'Potential to Erode Credibility'
The watchdog's statement declared: "The inquiry we conducted determined that the documentary's lack of disclosure that the narrator's father held a post in the Hamas-run government was substantially inaccurate.
"It meant that the public did not have critical information which may have been extremely pertinent to their evaluation of the voice and the information he presented.
"Trust is at the center of the bond between a television network and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the possibility to erode the exceptionally strong levels of credibility that the public would have invested in a BBC factual programme about the conflict in Gaza."
The programme was pulled from iPlayer in the month of February after the presenter's familial connections were revealed, and in the month of July an corporation's own inquiry concluded it infringed the organization's editorial guidelines on accuracy.
A representative for the broadcaster stated: "The Ofcom ruling is in accordance with the conclusions of the corporation's inquiry, that there was a significant failing in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the authority's determination in full. We will follow the directive as soon as the schedule and wording are confirmed."
