The British broadcaster was found to have committed a "significant breach" of media regulations by omitting to mention that the narrator of a programme about the Gaza situation was the child of a Hamas administrator, as ruled by regulatory body Ofcom.
An investigation by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The head of the BBC had already issued an apology, stating there had been "a significant failing in relation to truthfulness".
Ofcom has directed the corporation to broadcast a evening statement about its conclusions.
"Since this amounts to a serious breach of our rules, we are directing the broadcaster to broadcast a message of our conclusions against it on BBC2 at 9pm, with a schedule to be finalised," it said.
'Risk to Erode Credibility'
The watchdog's statement stated: "Our investigation found that the film's lack of disclosure that the narrator's male guardian occupied a role in the Hamas-controlled government was significantly deceptive.
"It meant that the public did not have essential details which may have been very significant to their judgment of the voice and the information he presented.
"Credibility is at the heart of the bond between a television network and its viewers, especially for a national broadcasting corporation such as the BBC.
"This oversight had the risk to undermine the exceptionally strong levels of credibility that audiences would have placed in a BBC factual programme about the conflict in Gaza."
The film was removed from iPlayer in February after the boy's personal associations came to light, and in July an broadcaster's internal assessment determined it violated the broadcaster's journalistic standards on factual correctness.
A corporation official commented: "The authority's determination is in line with the findings of the internal assessment, that there was a significant failing in the film in relation to the broadcaster's journalistic policies on truthfulness, which reflects clause 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the regulator's ruling in its entirety. We will comply with the directive as soon as the schedule and wording are confirmed."
