The public service broadcaster was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the presenter of a film about the Gaza conflict was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The head of the BBC had earlier expressed regret, saying there had been "a significant failing in relation to truthfulness".
The authority has instructed the corporation to broadcast a peak-time statement about its findings.
"Since this amounts to a major infringement of our rules, we are ordering the broadcaster to air a statement of our conclusions against it on BBC Two at 21:00, with a date to be finalised," the regulator stated.
'Possibility to Undermine Trust'
The authority's statement stated: "Our probe found that the programme's failure to disclose that the narrator's father served in a post in the Hamas-controlled administration was materially misleading.
"It meant that the viewers did not have critical information which may have been very significant to their assessment of the voice and the details he provided.
"Trust is at the center of the relationship between a television network and its public, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the potential to damage the very considerable degrees of trust that viewers would have invested in a factual film from the broadcaster about the conflict in Gaza."
The film was withdrawn from the online platform in the month of February after the narrator's familial connections emerged, and in this past July an corporation's own inquiry determined it violated the broadcaster's content policies on accuracy.
A corporation official said: "The regulator's decision is in accordance 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 truthfulness, which aligns with regulation 2.2 of the regulator's media standards.
"We have apologised for this and we agree with the regulator's ruling in full. We will comply with the sanction as soon as the timing and language are confirmed."
