The British broadcaster committed a "serious breach" of industry standards by not revealing that the presenter of a documentary about Gaza was the offspring of a Hamas representative, as determined by UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, stating there had been "a significant failing in relation to accuracy".
Ofcom has ordered the broadcaster to air a peak-time announcement about its decisions.
"As this represents a major infringement of our code, we are directing the BBC to air a announcement of our determinations against it on BBC Two at nine o'clock in the evening, with a timing to be determined," the statement read.
'Possibility to Undermine Trust'
The watchdog's announcement stated: "Our probe determined that the film's lack of disclosure that the presenter's father held a post in the Hamas-run authority was materially misleading.
"This implied that the public did not have vital facts which may have been highly relevant to their judgment of the narrator and the information he provided.
"Credibility is at the core of the connection between a media organization and its viewers, particularly for a public service broadcaster such as the BBC.
"This oversight had the possibility to erode the very considerable levels of trust that viewers would have put in a BBC factual programme about the conflict in Gaza."
The film was withdrawn from the online platform in February after the presenter's personal associations emerged, and in the month of July an broadcaster's internal assessment found it infringed the broadcaster's editorial guidelines on accuracy.
A corporation official stated: "The authority's determination is in line with the results 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 Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the regulator's ruling in full. We will comply with the directive as soon as the date and language are determined."
