The British broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the presenter of a programme about the Gaza conflict was the child of a Hamas representative, according to British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the documentary was "substantially inaccurate".
The BBC's director general had earlier expressed regret, noting there had been "a serious error in relation to accuracy".
The regulator has instructed the broadcaster to transmit a peak-time declaration about its findings.
"As this represents a serious breach of our rules, we are directing the broadcaster to broadcast a announcement of our determinations against it on BBC Two at nine o'clock in the evening, with a timing to be finalised," the regulator stated.
'Potential to Erode Credibility'
The watchdog's announcement stated: "The inquiry we conducted determined that the film's omission to reveal that the narrator's parent served in a role in the Hamas-administered government was materially misleading.
"Consequently that the audience did not have essential details which may have been highly relevant to their judgment of the voice and the information he presented.
"Trust is at the center of the connection between a broadcaster and its public, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the possibility to damage the very considerable degrees of trust that audiences would have invested in a BBC factual programme about the Gaza conflict."
The film was withdrawn from iPlayer in the month of February after the boy's family links emerged, and in the month of July an corporation's own inquiry found it violated the organization's journalistic standards on factual correctness.
A corporation official commented: "The regulator's decision is in accordance with the results of the internal assessment, that there was a significant failing in the film in relation to the corporation's content standards on factual correctness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in full. We will comply with the directive as soon as the date and wording are determined."
