The British broadcaster was found to have committed a "significant breach" of broadcasting rules by omitting to mention that the presenter of a film about the Gaza conflict was the offspring of a Hamas administrator, according to British broadcasting authority Ofcom.
An investigation by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the programme was "materially misleading".
The chief executive of the broadcaster had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The authority has ordered the BBC to air a peak-time announcement about its conclusions.
"Given this constitutes a serious breach of our code, we are instructing the corporation to transmit a message of our findings against it on BBC Two at 21:00, with a timing to be determined," the regulator stated.
'Potential to Undermine Credibility'
The authority's announcement said: "Our investigation found that the programme's omission to reveal that the narrator's male guardian occupied a position in the Hamas-run administration was substantially inaccurate.
"It meant that the public did not have critical information which may have been extremely pertinent to their judgment of the presenter and the information he shared.
"Trust is at the center of the bond between a media organization and its public, especially for a state-funded media outlet such as the public broadcaster.
"This oversight had the risk to damage the very considerable amounts of confidence that audiences would have invested in a documentary produced by the BBC about the conflict in Gaza."
The programme was pulled from iPlayer in last February after the narrator's personal associations came to light, and in the month of July an corporation's own inquiry concluded it violated the corporation's content policies on accuracy.
A corporation official commented: "The authority's determination is in accordance 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 factual correctness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the authority's determination in its entirety. We will follow the directive as soon as the date and wording are confirmed."
