The public service broadcaster was found to have committed a "serious breach" of broadcasting rules by not revealing that the presenter of a documentary about Gaza was the child of a Hamas representative, as determined by British broadcasting authority 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 previously apologised, saying there had been "a major oversight in relation to truthfulness".
The authority has ordered the BBC to transmit a prime-time declaration about its findings.
"Given this constitutes a major infringement of our regulations, we are ordering the BBC to broadcast a message of our conclusions against it on the BBC's second channel at 9pm, with a timing to be determined," it said.
'Risk to Damage Credibility'
The authority's report stated: "Our investigation determined that the documentary's lack of disclosure that the voice's male guardian served in a position in the Hamas-run authority was materially misleading.
"Consequently that the public did not have critical information which may have been highly relevant to their assessment of the narrator and the content he provided.
"Trust is at the heart of the bond between a media organization and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the potential to undermine the exceptionally strong amounts of credibility that the public would have placed in a factual film from the broadcaster about the conflict in Gaza."
The programme was withdrawn from the BBC's streaming service in the month of February after the presenter's personal associations were revealed, and in the month of July an broadcaster's internal assessment determined it violated the organization's content policies on factual correctness.
A representative for the broadcaster stated: "The regulator's decision is in line with the conclusions of the internal assessment, that there was a significant failing in the programme in relation to the corporation's content standards on accuracy, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we accept the regulator's ruling in its entirety. We will follow the directive as soon as the timing and wording are finalised."
