The public service broadcaster was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the narrator of a documentary about the Gaza situation was the offspring of a Hamas representative, according to British broadcasting authority Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to accuracy".
Ofcom has instructed the corporation to air a evening declaration about its conclusions.
"As this represents a serious breach of our code, we are instructing the broadcaster to air a announcement of our determinations against it on BBC Two at 21:00, with a date to be finalised," it said.
'Risk to Erode Confidence'
The authority's report declared: "The inquiry we conducted concluded that the documentary's omission to reveal that the narrator's father occupied a position in the Hamas-administered government was materially misleading.
"It meant that the audience did not have critical information which may have been extremely pertinent to their judgment of the narrator and the content he shared.
"Confidence is at the core of the bond between a media organization and its viewers, particularly for a public service broadcaster such as the public broadcaster.
"This oversight had the risk to erode the exceptionally strong levels of credibility that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The documentary was pulled from iPlayer in February after the boy's familial connections came to light, and in this past July an corporation's own inquiry found it infringed the organization's editorial guidelines on factual correctness.
A representative for the broadcaster commented: "The Ofcom ruling is in accordance with the results of the corporation's inquiry, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will follow the penalty as soon as the date and wording are determined."
