The British broadcaster was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the narrator of a programme about the Gaza situation was the offspring of a Hamas representative, according to regulatory body Ofcom.
An investigation by the media regulator 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 previously apologised, stating there had been "a significant failing in relation to truthfulness".
The regulator has instructed the corporation to broadcast a prime-time statement about its findings.
"As this represents a significant violation of our rules, we are instructing the broadcaster to transmit a announcement of our determinations against it on BBC2 at 21:00, with a schedule to be finalised," the statement read.
'Risk to Erode Confidence'
The authority's statement said: "The inquiry we conducted concluded that the film's omission to reveal that the presenter's father occupied a post in the Hamas-administered administration was significantly deceptive.
"This implied that the public did not have critical information which may have been very significant to their assessment of the narrator and the content he presented.
"Trust is at the center of the relationship between a broadcaster and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the risk to damage the exceptionally strong amounts of credibility that viewers would have placed in a BBC factual programme about the Israel-Gaza war."
The documentary was withdrawn from the online platform in February after the narrator's familial connections came to light, and in July an broadcaster's internal assessment determined it violated the broadcaster's content policies on accuracy.
A corporation official commented: "The Ofcom ruling is in agreement with the results of the corporation's inquiry, that there was a major oversight in the documentary in relation to the corporation's content standards on accuracy, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the authority's determination in complete. We will adhere to the directive as soon as the timing and language are determined."
