The BBC was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza conflict was the offspring of a Hamas representative, as determined by UK media regulator Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The BBC's director general had earlier expressed regret, stating there had been "a major oversight in relation to truthfulness".
Ofcom has instructed the corporation to broadcast a prime-time announcement about its findings.
"Given this constitutes a major infringement of our rules, we are instructing the BBC to transmit a announcement of our determinations against it on BBC2 at 21:00, with a date to be determined," the regulator stated.
'Possibility to Damage Confidence'
The regulator's report said: "The inquiry we conducted concluded that the documentary's failure to disclose that the narrator's father occupied a position in the Hamas-run authority was significantly deceptive.
"Consequently that the viewers did not have essential details which may have been very significant to their assessment of the voice and the details he presented.
"Credibility is at the core of the relationship between a television network and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the risk to undermine the very considerable amounts of confidence that viewers would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The programme was withdrawn from iPlayer in last February after the narrator's familial connections emerged, and in this past July an internal BBC review found it breached the organization's content policies on truthfulness.
A representative for the broadcaster commented: "The Ofcom ruling is in line with the findings of the internal assessment, that there was a major oversight in the documentary in relation to the corporation's content standards on factual correctness, which aligns with clause 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the regulator's ruling in its entirety. We will adhere to the directive as soon as the date and wording are confirmed."
