The public service broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the narrator of a film about the Gaza conflict was the son of a Hamas representative, as determined by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, noting there had been "a major oversight in relation to truthfulness".
Ofcom has instructed the broadcaster to air a prime-time declaration about its decisions.
"As this represents a significant violation of our rules, we are instructing the BBC to air a message of our findings against it on BBC Two at 21:00, with a timing to be finalised," the regulator stated.
'Potential to Erode Trust'
The regulator's report declared: "The inquiry we conducted concluded that the documentary's omission to reveal that the narrator's male guardian served in a post in the Hamas-controlled government was significantly deceptive.
"This implied that the viewers did not have critical information which may have been highly relevant to their assessment of the voice and the details he provided.
"Confidence is at the core of the connection between a broadcaster and its viewers, notably for a public service broadcaster such as the public broadcaster.
"This error had the possibility to damage the significantly high amounts of credibility that viewers would have put in a documentary produced by the BBC about the conflict in Gaza."
The film was removed from the online platform in the month of February after the presenter's familial connections were revealed, and in this past July an broadcaster's internal assessment concluded it infringed the corporation's editorial guidelines on accuracy.
A corporation official stated: "The regulator's decision is in line with the results of the corporation's inquiry, that there was a serious error in the documentary in relation to the BBC's Editorial Guidelines on accuracy, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will follow the sanction as soon as the schedule and language are finalised."
