The British broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the voice of a documentary about the Gaza conflict was the child of a Hamas representative, as determined by UK media regulator Ofcom.
An probe by Ofcom into the programme Gaza: How to Survive a Warzone has found that the programme was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a significant failing in relation to truthfulness".
The authority has instructed the BBC to air a peak-time statement about its conclusions.
"As this represents a serious breach of our code, we are instructing the corporation to transmit a statement of our conclusions against it on the BBC's second channel at 9pm, with a date to be confirmed," the statement read.
'Potential to Erode Confidence'
The regulator's report said: "The inquiry we conducted determined that the film's omission to reveal that the presenter's father served in a role in the Hamas-administered government was substantially inaccurate.
"Consequently that the viewers did not have essential details which may have been extremely pertinent to their judgment of the voice and the information he shared.
"Trust is at the center of the connection between a broadcaster and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the possibility to erode the significantly high degrees of confidence that the public would have put in a BBC factual programme about the conflict in Gaza."
The programme was pulled from iPlayer in February after the presenter's familial connections emerged, and in this past July an corporation's own inquiry determined it infringed the organization's journalistic standards on factual correctness.
A corporation official said: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a significant failing in the documentary in relation to the BBC's Editorial Guidelines on accuracy, which reflects clause 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the regulator's ruling in complete. We will adhere to the penalty as soon as the date and wording are determined."
