The public service broadcaster committed a "major breach" of media regulations by not revealing that the narrator of a documentary about Gaza was the child of a Hamas representative, as determined by 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 "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a significant failing in relation to accuracy".
The authority has directed the BBC to broadcast a prime-time statement about its conclusions.
"As this represents a serious breach of our regulations, we are directing the broadcaster to transmit a statement of our findings against it on BBC Two at 9pm, with a schedule to be confirmed," the statement read.
'Risk to Erode Credibility'
The watchdog's announcement stated: "Our investigation found that the programme's omission to reveal that the presenter's male guardian occupied a post in the Hamas-administered administration was materially misleading.
"Consequently that the public did not have critical information which may have been very significant to their evaluation of the narrator and the details he presented.
"Confidence is at the center of the connection between a media organization and its public, especially for a public service broadcaster such as the BBC.
"This oversight had the possibility to erode the very considerable amounts of trust that viewers would have invested in a BBC factual programme about the Gaza conflict."
The documentary was removed from the BBC's streaming service in February after the narrator's personal associations emerged, and in the month of July an corporation's own inquiry concluded it violated the organization's content policies on factual correctness.
A BBC spokesperson stated: "The Ofcom ruling is in accordance with the conclusions of Peter Johnston's review, that there was a major oversight in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which reflects Rule 2.2 of the regulator's media standards.
"We have apologised for this and we comply with the regulator's ruling in complete. We will comply with the directive as soon as the timing and wording are finalised."
