The British broadcaster committed a "significant breach" of broadcasting rules by not revealing that the presenter of a film about the Gaza situation was the offspring of a Hamas official, as ruled by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The chief executive of the broadcaster had previously apologised, saying there had been "a serious error in relation to truthfulness".
The regulator has directed the BBC to transmit a evening declaration about its conclusions.
"As this represents a significant violation of our rules, we are instructing the corporation to air a statement of our determinations against it on the BBC's second channel at 9pm, with a timing to be determined," the statement read.
'Risk to Undermine Credibility'
The watchdog's statement stated: "Our probe found that the programme's failure to disclose that the presenter's male guardian occupied a role in the Hamas-administered administration was significantly deceptive.
"Consequently that the public did not have vital facts which may have been very significant to their assessment of the presenter and the information he presented.
"Confidence is at the core of the relationship between a television network and its audience, especially for a public service broadcaster such as the BBC.
"This oversight had the possibility to erode the very considerable degrees of credibility that audiences would have placed in a BBC factual programme about the conflict in Gaza."
The film was pulled from iPlayer in the month of February after the narrator's personal associations were revealed, and in this past July an corporation's own inquiry found it breached the corporation's editorial guidelines on truthfulness.
A BBC spokesperson stated: "The authority's determination is in agreement with the findings of the corporation's inquiry, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on truthfulness, which aligns with clause 2.2 of the authority's broadcasting regulations.
"We issued an apology 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."
