The public service broadcaster was found to have committed a "major breach" of media regulations by failing to disclose that the narrator of a documentary about the Gaza situation was the offspring of a Hamas representative, according to UK media regulator Ofcom.
An probe by Ofcom into the programme Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The head of the BBC had already issued an apology, stating there had been "a significant failing in relation to factual correctness".
Ofcom has ordered the broadcaster to transmit a evening statement about its findings.
"Given this constitutes a significant violation of our code, we are directing the corporation to air a announcement of our findings against it on the BBC's second channel at 21:00, with a timing to be confirmed," the statement read.
'Risk to Erode Trust'
The authority's announcement declared: "The inquiry we conducted determined that the film's failure to disclose that the presenter's parent held a position in the Hamas-run administration was significantly deceptive.
"Consequently that the viewers did not have essential details which may have been highly relevant to their assessment of the presenter and the information he provided.
"Credibility is at the heart of the relationship between a media organization and its audience, notably for a state-funded media outlet such as the public broadcaster.
"This failing had the risk to undermine the significantly high levels of trust that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was withdrawn from the online platform in last February after the narrator's personal associations were revealed, and in July an internal BBC review determined it infringed the corporation's journalistic standards on factual correctness.
A representative for the broadcaster said: "The Ofcom ruling is in agreement with the results of the internal assessment, that there was a significant failing in the film in relation to the corporation's content standards on accuracy, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will follow the penalty as soon as the date and language are finalised."
