The British broadcaster engaged in a "significant breach" of industry standards by failing to disclose that the narrator of a programme about the Gaza conflict was the offspring of a Hamas official, as determined by regulatory body Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a significant failing in relation to accuracy".
The regulator has directed the corporation to transmit a prime-time announcement about its decisions.
"Given this constitutes a major infringement of our code, we are directing the corporation to broadcast a message of our determinations against it on BBC2 at 21:00, with a schedule to be confirmed," the statement read.
'Risk to Erode Confidence'
The regulator's announcement stated: "Our investigation found that the programme's failure to disclose that the voice's father held a post in the Hamas-run government was significantly deceptive.
"Consequently that the public did not have critical information which may have been extremely pertinent to their evaluation of the voice and the content he shared.
"Trust is at the core of the connection between a media organization and its audience, particularly for a national broadcasting corporation such as the public broadcaster.
"This oversight had the potential to erode the significantly high amounts of confidence that the public would have put in a documentary produced by the BBC about the conflict in Gaza."
The programme was removed from the online platform in the month of February after the narrator's familial connections emerged, and in the month of July an corporation's own inquiry found it infringed the corporation's content policies on truthfulness.
A corporation official commented: "The authority's determination is in accordance with the results of the internal assessment, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on truthfulness, which aligns with clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we agree with the authority's determination in complete. We will follow the penalty as soon as the schedule and language are confirmed."
