The British broadcaster was found to have committed a "serious breach" of media regulations by failing to disclose that the voice of a programme about the Gaza conflict was the son of a Hamas administrator, according to British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The BBC's director general had already issued an apology, noting there had been "a significant failing in relation to factual correctness".
The authority has ordered the BBC to broadcast a prime-time statement about its conclusions.
"Given this constitutes a significant violation of our code, we are directing the BBC to air a message of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a date to be determined," the regulator stated.
'Potential to Erode Trust'
The regulator's report stated: "The inquiry we conducted determined that the programme's lack of disclosure that the narrator's parent occupied a post in the Hamas-controlled administration was significantly deceptive.
"It meant that the viewers did not have critical information which may have been extremely pertinent to their evaluation of the narrator and the information he presented.
"Confidence is at the heart of the connection between a television network and its public, notably for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the possibility to erode the exceptionally strong levels of trust that audiences would have put in a documentary produced by the BBC about the Gaza conflict."
The documentary was removed from the BBC's streaming service in February after the boy's familial connections were revealed, and in this past July an broadcaster's internal assessment determined it violated the corporation's journalistic standards on factual correctness.
A corporation official said: "The authority's determination is in agreement with the conclusions of the corporation's inquiry, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on accuracy, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the authority's determination in its entirety. We will adhere to the directive as soon as the timing and language are confirmed."
