The British broadcaster engaged in a "serious breach" of broadcasting rules by not revealing that the voice of a programme about Gaza was the offspring of a Hamas representative, according to British broadcasting authority Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The BBC's director general had earlier expressed regret, stating there had been "a serious error in relation to accuracy".
Ofcom has instructed the BBC to broadcast a evening announcement about its decisions.
"Since this amounts to a major infringement of our code, we are instructing the BBC to broadcast a announcement of our determinations against it on the BBC's second channel at nine o'clock in the evening, with a date to be confirmed," the statement read.
'Risk to Damage Confidence'
The watchdog's report said: "Our investigation concluded that the programme's lack of disclosure that the narrator's parent served in a position in the Hamas-administered authority was materially misleading.
"Consequently that the public did not have vital facts which may have been extremely pertinent to their judgment of the voice and the details he provided.
"Trust is at the core of the connection between a television network and its public, especially for a public service broadcaster such as the BBC.
"This failing had the risk to damage the exceptionally strong degrees of credibility that audiences would have put in a documentary produced by the BBC about the Israel-Gaza war."
The programme was pulled from iPlayer in the month of February after the presenter's personal associations came to light, and in this past July an internal BBC review concluded it violated the organization's content policies on truthfulness.
A corporation official commented: "The regulator's decision is in line with the conclusions of the corporation's inquiry, that there was a major oversight in the programme in relation to the corporation's content standards on accuracy, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in full. We will follow the directive as soon as the timing and wording are finalised."
