The British broadcaster was found to have committed a "major breach" of media regulations by failing to disclose that the voice of a documentary about the Gaza situation was the child of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An inquiry by Ofcom into Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to accuracy".
The regulator has ordered the BBC to transmit a peak-time statement about its decisions.
"Since this amounts to a serious breach of our regulations, we are instructing the BBC to air a statement of our findings against it on BBC Two at 21:00, with a schedule to be determined," the regulator stated.
'Risk to Erode Credibility'
The regulator's announcement declared: "Our investigation concluded that the programme's failure to disclose that the voice's parent occupied a role in the Hamas-controlled administration was substantially inaccurate.
"This implied that the audience did not have essential details which may have been extremely pertinent to their judgment of the narrator and the content he provided.
"Trust is at the center of the bond between a television network and its viewers, especially for a state-funded media outlet such as the BBC.
"This failing had the possibility to erode the significantly high amounts of trust that audiences would have placed in a BBC factual programme about the conflict in Gaza."
The documentary was withdrawn from the BBC's streaming service in February after the presenter's personal associations emerged, and in the month of July an corporation's own inquiry determined it violated the broadcaster's editorial guidelines on accuracy.
A BBC spokesperson commented: "The authority's determination is in agreement with the conclusions of the corporation's inquiry, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the regulator's ruling in its entirety. We will follow the directive as soon as the timing and wording are determined."
