The BBC engaged in a "significant breach" of broadcasting rules by failing to disclose that the voice of a programme about the Gaza situation was the son of a Hamas official, as determined by UK media regulator Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a major oversight in relation to truthfulness".
The authority has directed the BBC to air a peak-time declaration about its findings.
"Given this constitutes a major infringement of our regulations, we are directing the corporation to broadcast a statement of our findings against it on BBC2 at nine o'clock in the evening, with a date to be determined," the regulator stated.
'Possibility to Erode Trust'
The regulator's statement stated: "The inquiry we conducted concluded that the programme's lack of disclosure that the presenter's father occupied a position in the Hamas-administered authority was significantly deceptive.
"Consequently that the viewers did not have critical information which may have been extremely pertinent to their evaluation of the voice and the information he provided.
"Credibility is at the center of the relationship between a media organization and its audience, notably for a state-funded media outlet such as the public broadcaster.
"This error had the risk to undermine the exceptionally strong levels of trust that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The documentary was removed from the online platform in the month of February after the boy's familial connections emerged, and in July an broadcaster's internal assessment found it infringed the broadcaster's content policies on truthfulness.
A BBC spokesperson said: "The Ofcom ruling is in agreement with the results of Peter Johnston's review, that there was a serious error in the programme in relation to the corporation's content standards on accuracy, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"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 timing and wording are confirmed."
