The public service broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the voice of a film about Gaza was the son of a Hamas official, as determined by regulatory body Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has found that the film was "significantly deceptive".
The head of the BBC had already issued an apology, stating there had been "a major oversight in relation to accuracy".
The authority has ordered the BBC to transmit a prime-time statement about its decisions.
"Since this amounts to a major infringement of our regulations, we are ordering the broadcaster to transmit a announcement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a timing to be determined," the regulator stated.
'Potential to Damage Trust'
The regulator's announcement said: "Our probe determined that the documentary's failure to disclose that the voice's male guardian occupied a role in the Hamas-controlled authority was substantially inaccurate.
"This implied that the viewers did not have critical information which may have been highly relevant to their evaluation of the presenter and the details he provided.
"Confidence is at the core of the connection between a television network and its audience, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the potential to erode the very considerable levels of trust that viewers would have placed in a factual film from the broadcaster about the Gaza conflict."
The film was pulled from iPlayer in the month of February after the boy's personal associations were revealed, and in this past July an internal BBC review found it violated the corporation's content policies on accuracy.
A corporation official commented: "The regulator's decision is in line with the conclusions of the internal assessment, that there was a major oversight in the programme in relation to the corporation's content standards on factual correctness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with the regulator's ruling in complete. We will adhere to the directive as soon as the timing and wording are confirmed."
