The British broadcaster was found to have committed a "major breach" of industry standards by failing to disclose that the presenter of a documentary about the Gaza conflict was the son of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An probe by Ofcom into the programme Gaza: How to Survive a Warzone has found that the film was "materially misleading".
The chief executive of the broadcaster had already issued an apology, stating there had been "a significant failing in relation to truthfulness".
The authority has directed the broadcaster to transmit a evening statement about its decisions.
"Since this amounts to a significant violation of our rules, we are directing the broadcaster to broadcast a statement of our findings against it on BBC Two at 21:00, with a schedule to be determined," the regulator stated.
'Possibility to Erode Credibility'
The authority's report stated: "The inquiry we conducted found that the documentary's lack of disclosure that the narrator's father served in a post in the Hamas-run government was significantly deceptive.
"This implied that the viewers did not have critical information which may have been highly relevant to their assessment of the narrator and the details he presented.
"Credibility is at the center of the bond between a broadcaster and its viewers, notably for a national broadcasting corporation such as the BBC.
"This failing had the possibility to erode the exceptionally strong levels of trust that audiences would have put in a factual film from the broadcaster about the conflict in Gaza."
The film was withdrawn from the online platform in the month of February after the boy's familial connections came to light, and in this past July an internal BBC review found it infringed the broadcaster's editorial guidelines on factual correctness.
A corporation official said: "The regulator's decision is in accordance with the findings of the internal assessment, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on accuracy, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in full. We will follow the penalty as soon as the date and wording are finalised."
