The British broadcaster engaged in a "serious breach" of media regulations by failing to disclose that the presenter of a film about Gaza was the son of a Hamas representative, as ruled by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The head of the BBC had earlier expressed regret, saying there had been "a significant failing in relation to factual correctness".
The regulator has instructed the corporation to transmit a peak-time declaration about its decisions.
"As this represents a significant violation of our regulations, we are directing the broadcaster to transmit a announcement of our determinations against it on BBC Two at 9pm, with a date to be finalised," the statement read.
'Potential to Erode Trust'
The regulator's report said: "Our probe determined that the film's lack of disclosure that the voice's male guardian held a post in the Hamas-run authority was substantially inaccurate.
"This implied 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.
"Credibility is at the center of the connection between a television network and its public, especially for a state-funded media outlet such as the BBC.
"This failing had the potential to undermine the significantly high levels of trust that audiences would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The film was withdrawn from the BBC's streaming service in the month of February after the narrator's familial connections were revealed, and in July an corporation's own inquiry found it violated the broadcaster's content policies on accuracy.
A representative for the broadcaster commented: "The regulator's decision is in agreement with the conclusions of Peter Johnston's review, that there was a serious error in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept the authority's determination in its entirety. We will adhere to the directive as soon as the schedule and language are confirmed."
