The British broadcaster was found to have committed a "serious breach" of media regulations by failing to disclose that the narrator of a programme about the Gaza conflict was the offspring of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An probe by the media regulator into Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The BBC's director general had previously apologised, saying there had been "a serious error in relation to factual correctness".
The regulator has instructed the corporation to broadcast a prime-time declaration about its findings.
"Since this amounts to a major infringement of our rules, we are ordering the corporation to transmit a announcement of our findings against it on the BBC's second channel at 21:00, with a timing to be finalised," the regulator stated.
'Risk to Undermine Confidence'
The watchdog's statement declared: "Our investigation found that the programme's lack of disclosure that the presenter's father occupied a role in the Hamas-controlled government was substantially inaccurate.
"Consequently that the public did not have critical information which may have been extremely pertinent to their judgment of the voice and the information he provided.
"Trust is at the core of the connection between a broadcaster and its audience, particularly for a public service broadcaster such as the public broadcaster.
"This oversight had the potential to damage the significantly high degrees of confidence that viewers would have placed in a factual film from the broadcaster about the Gaza conflict."
The film was removed from the BBC's streaming service in last February after the boy's personal associations were revealed, and in the month of July an broadcaster's internal assessment found it violated the corporation's content policies on factual correctness.
A corporation official commented: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on truthfulness, which reflects regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the regulator's ruling in complete. We will follow the penalty as soon as the date and wording are finalised."
