The public service broadcaster committed a "major breach" of broadcasting rules by not revealing that the voice of a film about the Gaza situation was the offspring of a Hamas official, according to regulatory body Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, stating there had been "a significant failing in relation to factual correctness".
The authority has instructed the corporation to air a evening announcement about its conclusions.
"Given this constitutes a significant violation of our regulations, we are ordering the corporation to transmit a announcement of our findings against it on BBC Two at 9pm, with a timing to be determined," the statement read.
'Risk to Erode Trust'
The watchdog's statement stated: "Our investigation concluded that the documentary's failure to disclose that the presenter's father held a post in the Hamas-controlled government was substantially inaccurate.
"This implied that the viewers did not have vital facts which may have been very significant to their evaluation of the presenter and the details he provided.
"Trust is at the core of the bond between a media organization and its viewers, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This error had the potential to undermine the exceptionally strong amounts of credibility that the public would have invested in a factual film from the broadcaster about the Gaza conflict."
The documentary was removed from the online platform in last February after the boy's personal associations emerged, and in the month of July an corporation's own inquiry determined it violated the broadcaster's journalistic standards on accuracy.
A representative for the broadcaster commented: "The regulator's decision is in accordance with the results of the corporation's inquiry, that there was a major oversight in the documentary in relation to the corporation's content standards on truthfulness, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will adhere to the directive as soon as the schedule and wording are determined."
