The public service broadcaster engaged in a "major breach" of media regulations by failing to disclose that the presenter of a film about the Gaza conflict was the offspring of a Hamas representative, according to UK media regulator Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a serious error in relation to accuracy".
Ofcom has instructed the broadcaster to air a evening declaration about its findings.
"Given this constitutes a serious breach of our regulations, we are instructing the broadcaster to air a statement of our findings against it on BBC Two at nine o'clock in the evening, with a schedule to be determined," the statement read.
'Risk to Erode Confidence'
The regulator's statement declared: "Our probe found that the film's failure to disclose that the voice's father served in a post in the Hamas-controlled administration was substantially inaccurate.
"It meant that the public did not have vital facts which may have been very significant to their assessment of the presenter and the content he shared.
"Confidence is at the heart of the relationship between a broadcaster and its public, especially for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the risk to damage the very considerable degrees of confidence that audiences would have invested in a documentary produced by the BBC about the conflict in Gaza."
The documentary was withdrawn from iPlayer in last February after the narrator's family links emerged, and in July an corporation's own inquiry determined it violated the corporation's content policies on truthfulness.
A representative for the broadcaster said: "The authority's determination is in line with the results of the internal assessment, that there was a serious error in the documentary in relation to the corporation's content standards on accuracy, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we accept the regulator's ruling in full. We will adhere to the directive as soon as the timing and language are determined."
