The BBC committed a "serious breach" of broadcasting rules by omitting to mention that the voice of a film about the Gaza conflict was the offspring of a Hamas administrator, according to UK media regulator Ofcom.
An probe by Ofcom into Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The BBC's director general had previously apologised, stating there had been "a major oversight in relation to truthfulness".
The regulator has ordered the corporation to air a peak-time announcement about its conclusions.
"Given this constitutes a major infringement of our regulations, we are ordering the broadcaster to broadcast a statement of our findings against it on BBC Two at 9pm, with a schedule to be determined," the statement read.
'Risk to Damage Confidence'
The watchdog's statement declared: "Our probe found that the programme's lack of disclosure that the voice's male guardian served in a position in the Hamas-run authority was materially misleading.
"It meant that the public did not have vital facts which may have been extremely pertinent to their judgment of the narrator and the information he shared.
"Trust is at the center of the bond between a television network and its public, notably for a public service broadcaster such as the BBC.
"This oversight had the possibility to undermine the significantly high levels of trust that audiences would have put in a factual film from the broadcaster about the conflict in Gaza."
The film was withdrawn from the online platform in the month of February after the boy's familial connections came to light, and in the month of July an broadcaster's internal assessment concluded it breached the organization's content policies on accuracy.
A BBC spokesperson said: "The authority's determination is in line with the findings of the corporation's inquiry, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on factual correctness, which aligns with regulation 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with Ofcom's decision in its entirety. We will adhere to the directive as soon as the date and wording are confirmed."
