The public service broadcaster committed a "major breach" of broadcasting rules by omitting to mention that the presenter of a documentary about the Gaza situation was the son of a Hamas official, 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 programme was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to truthfulness".
Ofcom has instructed the corporation to air a evening statement about its findings.
"As this represents a serious breach of our rules, we are instructing the BBC to air a message of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be determined," the statement read.
'Potential to Damage Confidence'
The regulator's statement stated: "Our probe found that the film's lack of disclosure that the voice's father held a role in the Hamas-controlled administration was significantly deceptive.
"Consequently that the audience did not have vital facts which may have been extremely pertinent to their assessment of the presenter and the information he shared.
"Confidence is at the center of the relationship between a media organization and its audience, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the very considerable levels of credibility that the public would have put in a factual film from the broadcaster about the Gaza conflict."
The documentary was removed from the BBC's streaming service in February after the narrator's personal associations came to light, and in this past July an corporation's own inquiry concluded it infringed the organization's content policies on factual correctness.
A corporation official stated: "The Ofcom ruling is in accordance with the conclusions of Peter Johnston's review, that there was a significant failing in the programme in relation to the corporation's content standards on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we agree with the regulator's ruling in full. We will follow the penalty as soon as the schedule and wording are finalised."
