The BBC was found to have committed a "major breach" of media regulations by not revealing that the voice of a programme about Gaza was the offspring of a Hamas administrator, according to British broadcasting authority Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to accuracy".
The regulator has directed the corporation to broadcast a evening statement about its findings.
"Since this amounts to a significant violation of our rules, we are directing the corporation to broadcast a message of our findings against it on BBC2 at nine o'clock in the evening, with a schedule to be finalised," the statement read.
'Risk to Damage Credibility'
The authority's report declared: "Our investigation determined that the programme's lack of disclosure that the narrator's father held a position in the Hamas-controlled administration was significantly deceptive.
"Consequently that the viewers did not have critical information which may have been very significant to their judgment of the voice and the content he shared.
"Credibility is at the center of the bond between a television network and its public, particularly for a national broadcasting corporation such as the BBC.
"This oversight had the risk to damage the exceptionally strong degrees of credibility that viewers would have put in a documentary produced by the BBC about the conflict in Gaza."
The programme was removed from the online platform in last February after the boy's family links came to light, and in the month of July an broadcaster's internal assessment determined it breached the corporation's content policies on accuracy.
A BBC spokesperson commented: "The authority's determination is in agreement with the conclusions of the internal assessment, that there was a major oversight in the film in relation to the corporation's content standards on factual correctness, which corresponds to Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we accept Ofcom's decision in full. We will adhere to the sanction as soon as the schedule and wording are finalised."
