The public service broadcaster engaged in a "major breach" of media regulations by omitting to mention that the presenter of a documentary about the Gaza conflict was the offspring of a Hamas representative, as determined by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The BBC's director general had already issued an apology, saying there had been "a major oversight in relation to factual correctness".
The regulator has instructed the corporation to transmit a evening statement about its decisions.
"As this represents a significant violation of our code, we are ordering the BBC to transmit a statement of our findings against it on BBC2 at 21:00, with a date to be determined," the regulator stated.
'Potential to Erode Confidence'
The authority's announcement said: "The inquiry we conducted determined that the film's failure to disclose that the voice's parent occupied a post in the Hamas-administered administration was substantially inaccurate.
"This implied that the public did not have essential details which may have been extremely pertinent to their judgment of the presenter and the content he presented.
"Confidence is at the core of the bond between a television network and its viewers, especially for a public service broadcaster such as the BBC.
"This failing had the risk to erode the very considerable degrees of credibility that audiences would have placed in a BBC factual programme about the Gaza conflict."
The programme was pulled from the online platform in February after the narrator's personal associations were revealed, and in July an corporation's own inquiry concluded it infringed the broadcaster's journalistic standards on accuracy.
A corporation official commented: "The regulator's decision is in accordance with the results of Peter Johnston's review, that there was a major oversight in the film in relation to the BBC's Editorial Guidelines on factual correctness, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the authority's determination in complete. We will follow the sanction as soon as the schedule and wording are finalised."
