The British broadcaster committed a "significant breach" of industry standards by omitting to mention that the narrator of a film about Gaza was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has concluded that the documentary was "materially misleading".
The BBC's director general had previously apologised, stating there had been "a significant failing in relation to accuracy".
Ofcom has directed the BBC to transmit a peak-time declaration about its decisions.
"Since this amounts to a significant violation of our code, we are instructing the BBC to transmit a statement of our findings against it on BBC Two at 9pm, with a date to be determined," the regulator stated.
'Risk to Damage Confidence'
The watchdog's report declared: "Our investigation determined that the film's failure to disclose that the narrator's father occupied a role in the Hamas-controlled administration was substantially inaccurate.
"It meant that the audience did not have critical information which may have been highly relevant to their evaluation of the narrator and the information he provided.
"Trust is at the center of the relationship between a media organization and its public, notably for a national broadcasting corporation such as the public broadcaster.
"This oversight had the risk to damage the significantly high amounts of credibility that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The documentary was pulled from iPlayer in the month of February after the narrator's familial connections were revealed, and in the month of July an corporation's own inquiry determined it violated the organization's content policies on truthfulness.
A representative for the broadcaster stated: "The authority's determination is in line with the results of the corporation's inquiry, that there was a serious error in the documentary in relation to the corporation's content standards on factual correctness, which reflects regulation 2.2 of the regulator's media standards.
"We expressed regret for this and we accept Ofcom's decision in its entirety. We will comply with the directive as soon as the schedule and wording are confirmed."
