The public service broadcaster was found to have committed a "significant breach" of broadcasting rules by omitting to mention that the narrator of a film about the Gaza situation was the offspring of a Hamas representative, according to British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The BBC's director general had previously apologised, noting there had been "a significant failing in relation to factual correctness".
Ofcom has directed the broadcaster to air a prime-time statement about its conclusions.
"As this represents a major infringement of our rules, we are directing the broadcaster to air a announcement of our determinations against it on the BBC's second channel at 9pm, with a date to be determined," it said.
'Possibility to Undermine Trust'
The authority's statement declared: "Our probe found that the programme's lack of disclosure that the narrator's male guardian occupied a role 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 narrator and the details he shared.
"Credibility is at the core of the connection between a television network and its audience, especially for a public service broadcaster such as the public broadcaster.
"This oversight had the possibility to damage the significantly high levels of credibility that audiences would have placed in a factual film from the broadcaster about the conflict in Gaza."
The film was pulled from iPlayer in last February after the narrator's family links emerged, and in the month of July an internal BBC review concluded it infringed the corporation's journalistic standards on truthfulness.
A BBC spokesperson stated: "The Ofcom ruling is in agreement with the findings of Peter Johnston's review, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on truthfulness, which reflects Rule 2.2 of the regulator's media standards.
"We have apologised for this and we agree with the regulator's ruling in its entirety. We will adhere to the directive as soon as the date and language are confirmed."
