The British broadcaster was found to have committed a "major breach" of media regulations by omitting to mention that the narrator of a documentary about the Gaza conflict was the child of a Hamas administrator, as ruled by regulatory body Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The head of the BBC had already issued an apology, noting there had been "a serious error in relation to truthfulness".
The authority has instructed the corporation to air a peak-time declaration about its findings.
"Given this constitutes a significant violation of our code, we are directing the broadcaster to air a statement of our conclusions against it on the BBC's second channel at 21:00, with a timing to be confirmed," the regulator stated.
'Potential to Damage Trust'
The regulator's announcement said: "Our investigation found that the film's failure to disclose that the voice's male guardian served in a role in the Hamas-controlled authority was substantially inaccurate.
"This implied that the public did not have critical information which may have been highly relevant to their judgment of the presenter and the details he shared.
"Credibility is at the center of the connection between a television network and its public, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the risk to undermine the very considerable amounts of credibility that audiences would have placed in a factual film from the broadcaster about the conflict in Gaza."
The programme was withdrawn from iPlayer in the month of February after the presenter's familial connections were revealed, and in the month of July an corporation's own inquiry concluded it infringed the organization's content policies on factual correctness.
A representative for the broadcaster commented: "The Ofcom ruling is in agreement with the results of the internal assessment, that there was a major oversight in the documentary in relation to the corporation's content standards on truthfulness, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the authority's determination in full. We will follow the sanction as soon as the timing and language are finalised."
