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 conflict was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The BBC's director general had previously apologised, saying there had been "a major oversight in relation to truthfulness".
The authority has ordered the corporation to air a prime-time statement about its conclusions.
"Given this constitutes a serious breach of our rules, we are instructing the BBC to broadcast a announcement of our conclusions against it on the BBC's second channel at 21:00, with a date to be finalised," the statement read.
'Possibility to Damage Trust'
The authority's statement stated: "Our probe concluded that the film's lack of disclosure that the narrator's father held a position in the Hamas-run authority was significantly deceptive.
"It meant that the public did not have critical information which may have been highly relevant to their judgment of the voice and the content he presented.
"Credibility is at the heart of the connection between a broadcaster and its public, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This error had the potential to undermine the significantly high amounts of trust that audiences would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The programme was removed from the online platform in the month of February after the presenter's family links emerged, and in this past July an broadcaster's internal assessment determined it violated the organization's content policies on truthfulness.
A BBC spokesperson said: "The Ofcom ruling is in accordance with the findings of the corporation's inquiry, that there was a serious error in the film in relation to the corporation's content standards on factual correctness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we agree with the regulator's ruling in full. We will comply with the directive as soon as the date and wording are determined."
