The British broadcaster was found to have committed a "significant breach" of broadcasting rules by omitting to mention that the narrator of a documentary about the Gaza conflict was the offspring of a Hamas official, as determined by British broadcasting authority Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "materially misleading".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to factual correctness".
The authority has ordered the broadcaster to transmit a prime-time announcement about its conclusions.
"As this represents a major infringement of our rules, we are instructing the corporation to broadcast a statement of our conclusions against it on the BBC's second channel at 9pm, with a date to be determined," it said.
'Potential to Erode Confidence'
The authority's announcement said: "Our probe concluded that the documentary's lack of disclosure that the narrator's male guardian held a role in the Hamas-administered government was substantially inaccurate.
"It meant that the audience did not have vital facts which may have been extremely pertinent to their evaluation of the narrator and the information he provided.
"Confidence is at the heart of the relationship between a television network and its audience, especially for a national broadcasting corporation such as the public broadcaster.
"This oversight had the possibility to undermine the exceptionally strong degrees of trust that audiences would have invested in a BBC factual programme about the conflict in Gaza."
The programme was withdrawn from the online platform in February after the boy's family links emerged, and in July an corporation's own inquiry determined it infringed the broadcaster's content policies on accuracy.
A representative for the broadcaster commented: "The regulator's decision is in accordance with the findings of Peter Johnston's review, that there was a serious error in the film in relation to the corporation's content standards on accuracy, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept the regulator's ruling in full. We will comply with the directive as soon as the schedule and wording are confirmed."
