The British broadcaster was found to have committed a "major breach" of industry standards by omitting to mention that the voice of a film about the Gaza situation was the child of a Hamas official, according to British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "materially misleading".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to factual correctness".
The regulator has ordered the broadcaster to broadcast a prime-time statement about its findings.
"Since this amounts to a serious breach of our rules, we are directing the BBC to broadcast a statement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a date to be determined," the statement read.
'Possibility to Damage Trust'
The regulator's report said: "Our investigation found that the programme's lack of disclosure that the voice's father served in a position in the Hamas-run government was significantly deceptive.
"Consequently that the audience did not have critical information which may have been extremely pertinent to their evaluation of the presenter and the content he shared.
"Trust is at the core of the connection between a television network and its audience, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the risk to erode the exceptionally strong amounts of credibility that viewers would have placed in a factual film from the broadcaster about the conflict in Gaza."
The programme was pulled from the BBC's streaming service in February after the narrator's personal associations came to light, and in the month of July an internal BBC review found it infringed the corporation's editorial guidelines on truthfulness.
A representative for the broadcaster said: "The Ofcom ruling is in agreement with the findings of the internal assessment, that there was a major oversight in the film in relation to the corporation's content standards on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in complete. We will adhere to the directive as soon as the timing and wording are confirmed."
