The public service broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the presenter of a programme about the Gaza conflict was the offspring of a Hamas official, as determined by UK media regulator Ofcom.
An probe by Ofcom into Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, saying there had been "a serious error in relation to truthfulness".
The authority has ordered the BBC to broadcast a prime-time statement about its decisions.
"Given this constitutes a serious breach of our rules, we are ordering the BBC to broadcast a statement of our findings against it on the BBC's second channel at 21:00, with a timing to be finalised," it said.
'Possibility to Erode Confidence'
The watchdog's statement declared: "The inquiry we conducted concluded that the programme's omission to reveal that the presenter's male guardian served in a role in the Hamas-administered administration was materially misleading.
"This implied that the public did not have essential details which may have been highly relevant to their evaluation of the narrator and the details he shared.
"Confidence is at the heart of the relationship between a television network and its audience, especially for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to damage the exceptionally strong degrees of confidence that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was removed from the BBC's streaming service in last February after the boy's familial connections emerged, and in this past July an corporation's own inquiry found it violated the organization's editorial guidelines on truthfulness.
A corporation official commented: "The Ofcom ruling is in line with the results of the corporation's inquiry, that there was a major oversight in the film in relation to the corporation's content standards on truthfulness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"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 date and wording are finalised."
