The public service broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the narrator of a programme about the Gaza conflict was the son of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to accuracy".
The regulator has instructed the corporation to broadcast a peak-time statement about its decisions.
"Since this amounts to a serious breach of our code, we are instructing the corporation to transmit a statement of our conclusions against it on BBC2 at 21:00, with a date to be determined," the statement read.
'Possibility to Damage Credibility'
The regulator's announcement declared: "The inquiry we conducted concluded that the documentary's omission to reveal that the presenter's parent occupied a position in the Hamas-run government was substantially inaccurate.
"It meant that the audience did not have critical information which may have been extremely pertinent to their evaluation of the voice and the details he shared.
"Credibility is at the heart of the relationship between a television network and its viewers, notably for a national broadcasting corporation such as the BBC.
"This oversight had the potential to erode the significantly high amounts of confidence that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The film was removed from the online platform in last February after the narrator's familial connections emerged, and in the month of July an internal BBC review concluded it breached the corporation's editorial guidelines on truthfulness.
A representative for the broadcaster said: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in full. We will follow the directive as soon as the date and wording are determined."
