The public service broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the presenter of a documentary about Gaza was the child of a Hamas representative, as ruled by regulatory body Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, noting there had been "a serious error in relation to factual correctness".
The authority has directed the corporation to transmit a prime-time announcement about its decisions.
"Given this constitutes a significant violation of our code, we are directing the corporation to broadcast a statement of our conclusions against it on BBC2 at nine o'clock in the evening, with a timing to be confirmed," the regulator stated.
'Potential to Undermine Credibility'
The regulator's statement declared: "Our investigation concluded that the documentary's failure to disclose that the narrator's parent occupied a role in the Hamas-controlled authority was significantly deceptive.
"This implied that the viewers did not have critical information which may have been extremely pertinent to their assessment of the narrator and the details he provided.
"Credibility is at the core of the relationship between a media organization and its public, notably for a public service broadcaster such as the public broadcaster.
"This failing had the risk to damage the very considerable levels of confidence that audiences would have put in a factual film from the broadcaster about the conflict in Gaza."
The film was withdrawn from iPlayer in the month of February after the narrator's family links came to light, and in this past July an corporation's own inquiry concluded it breached the organization's journalistic standards on accuracy.
A BBC spokesperson commented: "The Ofcom ruling is in line with the findings of the corporation's inquiry, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we agree with the authority's determination in full. We will comply with the directive as soon as the timing and wording are determined."
