The public service broadcaster was found to have committed a "major breach" of industry standards by not revealing that the presenter of a documentary about the Gaza situation was the son of a Hamas representative, as determined by regulatory body Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to truthfulness".
Ofcom has directed the BBC to air a prime-time announcement about its decisions.
"Given this constitutes a serious breach of our code, we are ordering the corporation to air a message of our findings against it on BBC2 at nine o'clock in the evening, with a timing to be determined," it said.
'Possibility to Damage Confidence'
The regulator's announcement stated: "Our investigation determined that the film's failure to disclose that the narrator's male guardian served in a role in the Hamas-controlled administration was significantly deceptive.
"It meant that the viewers did not have critical information which may have been extremely pertinent to their judgment of the presenter and the content he provided.
"Confidence is at the core of the relationship between a media organization and its public, especially for a public service broadcaster such as the BBC.
"This oversight had the potential to erode the very considerable degrees of credibility that audiences would have invested in a documentary produced by the BBC about the conflict in Gaza."
The documentary was pulled from the BBC's streaming service in the month of February after the presenter's personal associations came to light, and in the month of July an corporation's own inquiry found it violated the organization's content policies on truthfulness.
A representative for the broadcaster stated: "The authority's determination is in agreement with the conclusions of the corporation's inquiry, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on accuracy, which aligns with clause 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with the regulator's ruling in its entirety. We will comply with the directive as soon as the schedule and wording are confirmed."
