The British broadcaster was found to have committed a "major breach" of broadcasting rules by failing to disclose that the narrator of a film about Gaza was the offspring of a Hamas representative, as determined by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a serious error in relation to accuracy".
Ofcom has directed the BBC to air a evening statement about its conclusions.
"As this represents a significant violation of our rules, we are instructing the corporation to broadcast a message of our findings against it on BBC Two at 21:00, with a date to be determined," the statement read.
'Risk to Undermine Confidence'
The regulator's announcement said: "Our probe found that the film's lack of disclosure that the presenter's male guardian served in a post in the Hamas-run authority was substantially inaccurate.
"This implied that the public did not have vital facts which may have been very significant to their assessment of the presenter and the content he provided.
"Trust is at the center of the connection between a television network and its audience, especially for a public service broadcaster such as the BBC.
"This oversight had the potential to undermine the very considerable amounts of credibility that the public would have put in a factual film from the broadcaster about the conflict in Gaza."
The programme was withdrawn from the BBC's streaming service in the month of February after the narrator's personal associations came to light, and in this past July an internal BBC review found it breached the corporation's editorial guidelines on truthfulness.
A representative for the broadcaster said: "The authority's determination is in accordance with the conclusions of Peter Johnston's review, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on accuracy, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with Ofcom's decision in its entirety. We will adhere to the directive as soon as the schedule and wording are finalised."
