The public service broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the presenter of a film about the Gaza situation was the offspring of a Hamas representative, as determined by British broadcasting authority Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The BBC's director general had already issued an apology, stating there had been "a major oversight in relation to accuracy".
Ofcom has instructed the BBC to broadcast a evening statement about its decisions.
"As this represents a serious breach of our code, we are ordering the broadcaster to transmit a statement of our determinations against it on the BBC's second channel at 21:00, with a timing to be determined," the statement read.
'Possibility to Damage Credibility'
The regulator's announcement stated: "Our probe found that the programme's failure to disclose that the narrator's father occupied a post in the Hamas-run administration was materially misleading.
"Consequently that the viewers did not have vital facts which may have been very significant to their assessment of the presenter and the content he shared.
"Trust is at the core of the connection between a media organization and its public, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the possibility to undermine the very considerable degrees of confidence that viewers would have placed in a BBC factual programme about the Israel-Gaza war."
The film was removed from the BBC's streaming service in last February after the narrator's personal associations came to light, and in July an corporation's own inquiry found it infringed the broadcaster's content policies on truthfulness.
A BBC spokesperson commented: "The regulator's decision is in accordance with the results of the internal assessment, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on accuracy, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will follow the penalty as soon as the date and wording are determined."
