The BBC was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the presenter of a film about the Gaza conflict was the offspring of a Hamas official, as determined by British broadcasting authority Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to factual correctness".
Ofcom has instructed the corporation to air a peak-time declaration about its conclusions.
"Since this amounts to a serious breach of our regulations, we are ordering the BBC to transmit a announcement of our findings against it on BBC2 at 9pm, with a schedule to be confirmed," it said.
'Possibility to Damage Confidence'
The regulator's report said: "Our probe determined that the programme's lack of disclosure that the voice's male guardian occupied a position in the Hamas-controlled authority was substantially inaccurate.
"This implied that the audience did not have critical information which may have been very significant to their judgment of the voice and the details he presented.
"Confidence is at the core of the bond between a broadcaster and its viewers, notably for a national broadcasting corporation such as the BBC.
"This failing had the possibility to undermine the exceptionally strong amounts of credibility that the public would have placed in a factual film from the broadcaster about the Israel-Gaza war."
The film was removed from iPlayer in the month of February after the boy's personal associations came to light, and in July an internal BBC review determined it violated the corporation's content policies on accuracy.
A representative for the broadcaster stated: "The authority's determination is in agreement with the findings of the corporation's inquiry, that there was a significant failing in the film in relation to the corporation's content standards on factual correctness, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with Ofcom's decision in full. We will follow the penalty as soon as the schedule and language are confirmed."
