The British broadcaster was found to have committed a "serious breach" of broadcasting rules by not revealing that the narrator of a documentary about the Gaza situation was the son of a Hamas official, as ruled by British broadcasting authority Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a significant failing in relation to factual correctness".
The authority has directed the corporation to transmit a evening announcement about its conclusions.
"Since this amounts to a major infringement of our rules, we are directing the corporation to transmit a announcement of our findings against it on the BBC's second channel at 21:00, with a timing to be finalised," the statement read.
'Potential to Undermine Credibility'
The watchdog's announcement said: "The inquiry we conducted concluded that the film's failure to disclose that the presenter's parent held a post in the Hamas-controlled administration was significantly deceptive.
"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 presented.
"Confidence is at the heart of the connection between a media organization and its public, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This failing had the possibility to erode the very considerable degrees of credibility that the public would have invested in a BBC factual programme about the conflict in Gaza."
The programme was removed from the online platform in the month of February after the narrator's familial connections were revealed, and in this past July an corporation's own inquiry determined it violated the broadcaster's content policies on truthfulness.
A corporation official commented: "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 broadcaster's journalistic policies on truthfulness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we agree with the regulator's ruling in its entirety. We will follow the sanction as soon as the date and wording are determined."
