The British broadcaster was found to have committed a "serious breach" of media regulations by not revealing that the narrator of a film about the Gaza situation was the child of a Hamas representative, as determined by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, stating there had been "a major oversight in relation to accuracy".
The regulator has directed the corporation to broadcast a evening statement about its conclusions.
"As this represents a major infringement of our code, we are instructing the broadcaster to broadcast a announcement of our findings against it on the BBC's second channel at 21:00, with a timing to be confirmed," the regulator stated.
'Risk to Damage Confidence'
The regulator's announcement stated: "Our investigation concluded that the programme's failure to disclose that the presenter's male guardian held a post in the Hamas-controlled administration was materially misleading.
"Consequently that the public did not have essential details which may have been highly relevant to their evaluation of the presenter and the details he provided.
"Credibility is at the core of the bond between a media organization and its public, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the risk to damage the significantly high amounts of trust that the public would have put in a documentary produced by the BBC about the Gaza conflict."
The film was removed from the BBC's streaming service in the month of February after the narrator's familial connections were revealed, and in July an corporation's own inquiry found it breached the corporation's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The Ofcom ruling is in agreement with the findings of the internal assessment, that there was a significant failing in the film in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with the regulator's ruling in its entirety. We will follow the penalty as soon as the schedule and language are confirmed."
