The British broadcaster was found to have committed a "major breach" of industry standards by not revealing that the voice of a film about the Gaza conflict was the son of a Hamas administrator, as determined by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "substantially inaccurate".
The head of the BBC had already issued an apology, saying there had been "a major oversight in relation to accuracy".
The authority has directed the broadcaster to transmit a prime-time announcement about its decisions.
"As this represents a major infringement of our code, we are directing the BBC to transmit a message of our determinations against it on BBC2 at 9pm, with a date to be confirmed," the statement read.
'Potential to Undermine Credibility'
The authority's announcement said: "Our investigation concluded that the documentary's omission to reveal that the narrator's father held a role in the Hamas-controlled administration was significantly deceptive.
"Consequently that the audience did not have essential details which may have been very significant to their evaluation of the presenter and the content he provided.
"Trust is at the center of the bond between a broadcaster and its viewers, notably for a public service broadcaster such as the BBC.
"This error had the possibility to damage the very considerable degrees of credibility that the public would have placed in a documentary produced by the BBC about the conflict in Gaza."
The programme was withdrawn from the online platform in the month of February after the boy's familial connections emerged, and in the month of July an broadcaster's internal assessment determined it infringed the organization's editorial guidelines on truthfulness.
A BBC spokesperson commented: "The authority's determination is in agreement with the conclusions of the internal assessment, that there was a significant failing in the documentary in relation to the corporation's content standards on factual correctness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with Ofcom's decision in full. We will comply with the directive as soon as the schedule and language are confirmed."
