The BBC committed a "significant breach" of media regulations by failing to disclose that the presenter of a programme about the Gaza situation was the son of a Hamas official, as determined by UK media regulator Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The head of the BBC had previously apologised, saying there had been "a serious error in relation to factual correctness".
The authority has instructed the corporation to transmit a evening announcement about its decisions.
"As this represents a major infringement of our rules, we are instructing the corporation 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 confirmed," the regulator stated.
'Potential to Erode Credibility'
The authority's announcement stated: "Our investigation concluded that the documentary's omission to reveal that the voice's parent occupied a position in the Hamas-controlled administration was significantly deceptive.
"Consequently that the public did not have essential details which may have been highly relevant to their judgment of the presenter and the content he provided.
"Confidence is at the center of the connection between a broadcaster and its audience, notably for a public service broadcaster such as the BBC.
"This failing had the possibility to erode the exceptionally strong levels of credibility that viewers would have put in a BBC factual programme about the Gaza conflict."
The programme was withdrawn from the BBC's streaming service in the month of February after the presenter's familial connections emerged, and in the month of July an internal BBC review found it violated the organization's journalistic standards on accuracy.
A BBC spokesperson stated: "The Ofcom ruling is in line with the findings of the internal assessment, that there was a major oversight in the documentary in relation to the corporation's content standards on accuracy, which reflects clause 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with the regulator's ruling in its entirety. We will comply with the penalty as soon as the timing and language are determined."
