The public service broadcaster engaged in a "significant breach" of broadcasting rules by failing to disclose that the presenter of a film about the Gaza situation was the child of a Hamas representative, according to regulatory body Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The head of the BBC had previously apologised, noting there had been "a significant failing in relation to truthfulness".
The regulator has ordered the broadcaster to air a peak-time declaration about its conclusions.
"Since this amounts to a significant violation of our regulations, we are directing the corporation to air a statement of our conclusions against it on BBC2 at nine o'clock in the evening, with a timing to be determined," the statement read.
'Risk to Damage Confidence'
The watchdog's report said: "The inquiry we conducted concluded that the programme's omission to reveal that the narrator's father occupied a position in the Hamas-controlled government was materially misleading.
"This implied that the viewers did not have vital facts which may have been extremely pertinent to their evaluation of the presenter and the information he presented.
"Trust is at the heart of the bond between a broadcaster and its viewers, notably for a public service broadcaster such as the BBC.
"This failing had the risk to erode the significantly high degrees of credibility that viewers would have put in a factual film from the broadcaster about the conflict in Gaza."
The film was removed from iPlayer in the month of February after the boy's family links were revealed, and in this past July an internal BBC review determined it violated the corporation's journalistic standards on factual correctness.
A representative for the broadcaster stated: "The authority's determination is in agreement with the results of the internal assessment, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on accuracy, which aligns with regulation 2.2 of the regulator's media standards.
"We have apologised for this and we accept Ofcom's decision in complete. We will follow the directive as soon as the schedule and language are confirmed."
