The public service broadcaster was found to have committed a "significant breach" of industry standards by not revealing that the narrator of a film about Gaza was the child of a Hamas administrator, according to UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a significant failing in relation to truthfulness".
The regulator has ordered the corporation to broadcast a peak-time statement about its conclusions.
"Given this constitutes a significant violation of our code, we are directing the BBC to transmit a statement of our determinations against it on BBC2 at 21:00, with a schedule to be determined," it said.
'Possibility to Undermine Confidence'
The watchdog's report stated: "The inquiry we conducted concluded that the programme's lack of disclosure that the narrator's father occupied a post in the Hamas-run government was materially misleading.
"Consequently that the audience did not have critical information which may have been very significant to their evaluation of the narrator and the content he shared.
"Trust is at the heart of the bond between a media organization and its viewers, notably for a national broadcasting corporation such as the BBC.
"This oversight had the risk to undermine the exceptionally strong degrees of trust that viewers would have put in a BBC factual programme about the Israel-Gaza war."
The film was pulled from iPlayer in February after the presenter's personal associations came to light, and in the month of July an internal BBC review determined it violated the corporation's content policies on accuracy.
A representative for the broadcaster stated: "The authority's determination is in accordance with the results of the internal assessment, that there was a significant failing in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we accept the authority's determination in its entirety. We will comply with the directive as soon as the timing and wording are finalised."
