The public service broadcaster committed a "significant breach" of broadcasting rules by failing to disclose that the presenter of a film about the Gaza situation was the child of a Hamas representative, according to UK media regulator Ofcom.
An investigation by Ofcom into Gaza: How to Survive a Warzone has determined that the film was "substantially inaccurate".
The head of the BBC had already issued an apology, stating there had been "a significant failing in relation to accuracy".
The regulator has directed the corporation to broadcast a evening declaration about its decisions.
"Since this amounts to a major infringement of our regulations, we are ordering the broadcaster to broadcast 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.
'Risk to Undermine Credibility'
The watchdog's announcement declared: "Our investigation found that the programme's failure to disclose that the presenter's parent held a role in the Hamas-administered government was substantially inaccurate.
"It meant that the viewers did not have critical information which may have been very significant to their judgment of the presenter and the information he provided.
"Confidence is at the center of the relationship between a television network and its audience, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the potential to damage the exceptionally strong levels of credibility that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The film was withdrawn from the online platform in February after the narrator's family links came to light, and in July an corporation's own inquiry determined it breached the organization's journalistic standards on accuracy.
A BBC spokesperson stated: "The Ofcom ruling is in line with the results of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on truthfulness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the authority's determination in its entirety. We will comply with the penalty as soon as the timing and wording are finalised."
