The public service broadcaster was found to have committed a "major breach" of broadcasting rules by failing to disclose that the narrator of a documentary about Gaza was the son of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The head of the BBC had previously apologised, noting there had been "a major oversight in relation to factual correctness".
The regulator has ordered the BBC to transmit a peak-time statement about its findings.
"As this represents a significant violation of our code, we are ordering the corporation to air a statement of our findings against it on BBC2 at 21:00, with a timing to be finalised," the regulator stated.
'Possibility to Undermine Confidence'
The authority's statement said: "The inquiry we conducted determined that the documentary's omission to reveal that the voice's male guardian occupied a role in the Hamas-administered government was materially misleading.
"Consequently that the viewers did not have vital facts which may have been highly relevant to their judgment of the presenter and the details he shared.
"Trust is at the core of the relationship between a television network and its public, notably for a national broadcasting corporation such as the public broadcaster.
"This failing had the potential to damage the significantly high degrees of trust that viewers would have put in a documentary produced by the BBC about the Israel-Gaza war."
The programme was pulled from the BBC's streaming service in last February after the boy's personal associations came to light, and in the month of July an broadcaster's internal assessment concluded it infringed the corporation's editorial guidelines on accuracy.
A representative for the broadcaster commented: "The authority's determination is in line with the conclusions of the internal assessment, that there was a serious error in the documentary in relation to the corporation's content standards on factual correctness, which corresponds to regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will comply with the sanction as soon as the schedule and wording are confirmed."
