The British broadcaster was found to have committed a "significant breach" of broadcasting rules by not revealing that the presenter of a documentary about the Gaza situation was the child of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An probe by Ofcom into Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, noting there had been "a major oversight in relation to truthfulness".
The regulator has ordered the corporation to broadcast a prime-time declaration about its conclusions.
"Since this amounts to a serious breach of our code, we are ordering the broadcaster to transmit a announcement of our conclusions against it on BBC2 at 9pm, with a timing to be finalised," the statement read.
'Potential to Erode Confidence'
The watchdog's announcement stated: "The inquiry we conducted determined that the film's failure to disclose that the narrator's father served in a role in the Hamas-administered administration was significantly deceptive.
"It meant that the audience did not have essential details which may have been very significant to their evaluation of the narrator and the information he presented.
"Credibility is at the center of the connection between a television network and its viewers, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This error had the risk to undermine the exceptionally strong amounts of confidence that the public would have invested in a factual film from the broadcaster about the Israel-Gaza war."
The film was removed from iPlayer in last February after the presenter's familial connections were revealed, and in July an internal BBC review found it breached the organization's content policies on truthfulness.
A corporation official stated: "The Ofcom ruling is in accordance with the results of the corporation's inquiry, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on factual correctness, which reflects Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with the authority's determination in complete. We will comply with the directive as soon as the schedule and wording are determined."
