The British broadcaster was found to have committed a "serious breach" of industry standards by omitting to mention that the narrator of a documentary about the Gaza conflict was the child of a Hamas official, as ruled by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, noting there had been "a significant failing in relation to factual correctness".
Ofcom has instructed the corporation to transmit a peak-time statement about its decisions.
"Given this constitutes a serious breach of our regulations, we are directing the BBC to broadcast a statement of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a date to be determined," it said.
'Potential to Erode Credibility'
The regulator's report said: "Our probe concluded that the film's failure to disclose that the narrator's male guardian served in a role in the Hamas-run government was substantially inaccurate.
"Consequently that the public did not have vital facts which may have been very significant to their judgment of the presenter and the information he shared.
"Confidence is at the core of the connection between a television network and its public, especially for a national broadcasting corporation such as the BBC.
"This oversight had the possibility to undermine the exceptionally strong levels of trust that audiences would have placed in a BBC factual programme about the conflict in Gaza."
The documentary was removed from the BBC's streaming service in last February after the narrator's family links emerged, and in July an corporation's own inquiry determined it infringed the broadcaster's editorial guidelines on truthfulness.
A representative for the broadcaster stated: "The regulator's decision is in accordance with the results of Peter Johnston's review, that there was a significant failing in the documentary in relation to the corporation's content standards on truthfulness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept Ofcom's decision in complete. We will follow the directive as soon as the date and wording are confirmed."
