The British broadcaster committed a "serious breach" of industry standards by omitting to mention that the narrator of a film about the Gaza conflict was the offspring of a Hamas official, as determined by UK media regulator Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, noting there had been "a major oversight in relation to truthfulness".
The regulator has instructed the broadcaster to broadcast a peak-time statement about its conclusions.
"As this represents a major infringement of our regulations, we are instructing the BBC to air a statement of our findings against it on the BBC's second channel at 21:00, with a timing to be finalised," the statement read.
'Possibility to Undermine Confidence'
The watchdog's report said: "The inquiry we conducted determined that the programme's lack of disclosure that the presenter's parent served in a role in the Hamas-controlled government was materially misleading.
"Consequently that the audience did not have critical information which may have been highly relevant to their judgment of the voice and the information he shared.
"Confidence is at the heart of the relationship between a media organization and its viewers, notably for a state-funded media outlet such as the BBC.
"This failing had the risk to damage the exceptionally strong levels of confidence that viewers would have placed in a BBC factual programme about the Israel-Gaza war."
The documentary was pulled from the BBC's streaming service in February after the narrator's personal associations came to light, and in the month of July an corporation's own inquiry determined it infringed the organization's journalistic standards on factual correctness.
A corporation official stated: "The Ofcom ruling is in accordance with the results of the corporation's inquiry, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which reflects Rule 2.2 of the regulator's media standards.
"We have apologised for this and we accept Ofcom's decision in complete. We will follow the directive as soon as the timing and wording are finalised."
