The BBC committed a "major breach" of media regulations by omitting to mention that the narrator of a film about Gaza was the son of a Hamas administrator, according to regulatory body Ofcom.
An probe by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "significantly deceptive".
The BBC's director general had already issued an apology, noting there had been "a significant failing in relation to truthfulness".
The authority has ordered the corporation to broadcast a peak-time statement about its findings.
"Given this constitutes a major infringement of our code, we are ordering the broadcaster to broadcast a statement of our findings against it on BBC2 at 21:00, with a timing to be confirmed," the statement read.
'Possibility to Undermine Credibility'
The watchdog's announcement said: "Our investigation determined that the programme's lack of disclosure that the narrator's male guardian served in a position in the Hamas-administered government was materially misleading.
"Consequently that the public did not have essential details which may have been very significant to their evaluation of the presenter and the details he provided.
"Credibility is at the center of the connection between a media organization and its viewers, notably for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the possibility to erode the exceptionally strong degrees of confidence that viewers would have placed in a factual film from the broadcaster about the conflict in Gaza."
The film was withdrawn from iPlayer in the month of February after the boy's personal associations emerged, and in July an internal BBC review concluded it infringed the organization's editorial guidelines on truthfulness.
A corporation official stated: "The regulator's decision is in agreement with the conclusions of the internal assessment, that there was a major oversight in the programme in relation to the corporation's content standards on accuracy, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept Ofcom's decision in full. We will follow the directive as soon as the date and language are determined."
