The British broadcaster engaged in a "serious breach" of broadcasting rules by failing to disclose that the narrator of a film about the Gaza situation was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, noting there had been "a serious error in relation to accuracy".
The authority has ordered the BBC to broadcast a peak-time announcement about its decisions.
"As this represents a major infringement of our regulations, we are instructing the corporation to broadcast a announcement of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a timing to be determined," it said.
'Potential to Damage Confidence'
The authority's report declared: "Our probe determined that the film's lack of disclosure that the narrator's male guardian served in a post in the Hamas-run authority was substantially inaccurate.
"This implied that the audience did not have vital facts which may have been very significant to their assessment of the voice and the information he shared.
"Trust is at the center of the relationship between a television network and its public, especially for a public service broadcaster such as the BBC.
"This error had the risk to damage the significantly high degrees of confidence that the public would have invested in a documentary produced by the BBC about the Israel-Gaza war."
The film was withdrawn from the online platform in February after the presenter's familial connections were revealed, and in the month of July an corporation's own inquiry found it breached the organization's editorial guidelines on factual correctness.
A BBC spokesperson commented: "The regulator's decision is in accordance with the findings of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on factual correctness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will adhere to the directive as soon as the date and language are confirmed."
