The BBC committed a "significant breach" of broadcasting rules by omitting to mention that the voice of a programme about the Gaza situation was the offspring of a Hamas official, as ruled by regulatory body Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The head of the BBC had earlier expressed regret, stating there had been "a major oversight in relation to truthfulness".
The regulator has instructed the BBC to transmit a prime-time declaration about its conclusions.
"As this represents a major infringement of our code, we are instructing the BBC to air a message of our determinations against it on the BBC's second channel at 9pm, with a date to be confirmed," the regulator stated.
'Risk to Undermine Credibility'
The watchdog's report declared: "The inquiry we conducted determined that the film's lack of disclosure that the voice's parent held a position in the Hamas-controlled government was substantially inaccurate.
"It meant that the viewers did not have critical information which may have been very significant to their evaluation of the presenter and the content he provided.
"Credibility is at the heart of the relationship between a television network and its viewers, particularly for a state-funded media outlet such as the BBC.
"This failing had the possibility to erode the very considerable amounts of trust that audiences would have placed in a factual film from the broadcaster about the Gaza conflict."
The film was withdrawn from the online platform in the month of February after the boy's personal associations were revealed, and in the month of July an corporation's own inquiry concluded it infringed the broadcaster's editorial guidelines on accuracy.
A BBC spokesperson stated: "The authority's determination is in agreement with the findings of the internal assessment, that there was a major oversight in the documentary in relation to the corporation's content standards on accuracy, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with the authority's determination in complete. We will adhere to the directive as soon as the timing and wording are finalised."
