The British broadcaster committed a "major breach" of industry standards by not revealing that the narrator of a documentary about Gaza was the child of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a serious error in relation to truthfulness".
Ofcom has instructed the corporation to air a evening announcement about its decisions.
"Given this constitutes a major infringement of our regulations, we are directing the broadcaster to air a statement of our determinations against it on BBC2 at 9pm, with a timing to be determined," the regulator stated.
'Potential to Undermine Credibility'
The watchdog's statement said: "Our probe determined that the film's lack of disclosure that the presenter's father occupied a post in the Hamas-controlled authority was significantly deceptive.
"This implied that the audience did not have critical information which may have been extremely pertinent to their assessment of the voice and the information he shared.
"Trust is at the center of the bond between a media organization and its public, particularly for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the potential to damage the exceptionally strong degrees of credibility that audiences would have invested in a factual film from the broadcaster about the Gaza conflict."
The documentary was pulled from the online platform in the month of February after the boy's family links emerged, and in the month of July an corporation's own inquiry found it infringed the broadcaster's editorial guidelines on factual correctness.
A BBC spokesperson said: "The Ofcom ruling is in accordance with the results of Peter Johnston's review, that there was a significant failing in the programme in relation to the corporation's content standards on factual correctness, which aligns with Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will comply with the penalty as soon as the date and wording are finalised."
