The British broadcaster was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the narrator of a documentary about Gaza was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a major oversight in relation to factual correctness".
Ofcom has instructed the broadcaster to broadcast a evening declaration about its findings.
"As this represents a serious breach of our code, we are directing the BBC to transmit a message of our conclusions against it on BBC2 at 21:00, with a date to be confirmed," the statement read.
'Potential to Undermine Credibility'
The watchdog's announcement declared: "Our probe found that the film's lack of disclosure that the voice's male guardian served in a post in the Hamas-controlled authority was significantly deceptive.
"It meant that the viewers did not have vital facts which may have been highly relevant to their assessment of the presenter and the details he shared.
"Credibility is at the center of the relationship between a television network and its audience, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the exceptionally strong amounts of trust that audiences would have placed in a factual film from the broadcaster about the conflict in Gaza."
The programme was removed from the BBC's streaming service in last February after the presenter's familial connections emerged, and in July an broadcaster's internal assessment determined it infringed the broadcaster's editorial guidelines on accuracy.
A corporation official commented: "The Ofcom ruling is in agreement with the findings of the internal assessment, that there was a major oversight in the documentary in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept Ofcom's decision in complete. We will comply with the sanction as soon as the date and language are determined."
