The public service broadcaster committed a "significant breach" of broadcasting rules by failing to disclose that the presenter of a film about Gaza was the son of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a significant failing in relation to factual correctness".
Ofcom has directed the broadcaster to air a prime-time announcement about its conclusions.
"As this represents a serious breach of our rules, we are ordering the corporation to transmit a statement of our determinations against it on BBC2 at 9pm, with a schedule to be confirmed," the regulator stated.
'Potential to Damage Confidence'
The watchdog's announcement stated: "The inquiry we conducted determined that the documentary's failure to disclose that the narrator's parent held a post in the Hamas-administered authority was materially misleading.
"Consequently that the viewers did not have vital facts which may have been very significant to their assessment of the narrator and the information he provided.
"Confidence is at the center of the connection between a television network and its audience, particularly for a public service broadcaster such as the BBC.
"This failing had the potential to damage the exceptionally strong degrees of confidence that viewers would have put in a factual film from the broadcaster about the Gaza conflict."
The film was pulled from the BBC's streaming service in last February after the boy's family links emerged, and in this past July an broadcaster's internal assessment concluded it breached the organization's content policies on accuracy.
A corporation official stated: "The authority's determination is in line with the results of Peter Johnston's review, that there was a major oversight in the documentary in relation to the corporation's content standards on factual correctness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"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 determined."
