The public service broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the presenter of a documentary about the Gaza conflict was the child of a Hamas administrator, according to UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The chief executive of the broadcaster had previously apologised, saying there had been "a serious error in relation to accuracy".
Ofcom has instructed the broadcaster to broadcast a peak-time statement about its conclusions.
"Since this amounts to a major infringement of our regulations, we are ordering the BBC to transmit a statement of our conclusions against it on BBC Two at 21:00, with a schedule to be finalised," the statement read.
'Risk to Undermine Trust'
The watchdog's statement said: "Our investigation concluded that the documentary's lack of disclosure that the presenter's male guardian held a post in the Hamas-administered government was substantially inaccurate.
"This implied that the public did not have critical information which may have been highly relevant to their evaluation of the presenter and the content he presented.
"Credibility is at the core of the bond between a broadcaster and its audience, notably for a public service broadcaster such as the BBC.
"This oversight had the risk to erode the significantly high levels of trust that audiences would have put in a documentary produced by the BBC about the conflict in Gaza."
The film was pulled from the online platform in February after the boy's family links came to light, and in the month of July an broadcaster's internal assessment determined it violated the broadcaster's editorial guidelines on truthfulness.
A corporation official said: "The authority's determination is in agreement with the findings of the internal assessment, that there was a serious error in the film in relation to the corporation's content standards on factual correctness, which aligns with Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with the authority's determination in full. We will adhere to the directive as soon as the date and wording are determined."
