The BBC was found to have committed a "serious breach" of industry standards by not revealing that the presenter of a programme about the Gaza conflict was the son of a Hamas administrator, as ruled by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had already issued an apology, noting there had been "a major oversight in relation to accuracy".
The regulator has ordered the BBC to broadcast a peak-time announcement about its decisions.
"Since this amounts to a serious breach of our regulations, we are ordering the BBC to air a message of our conclusions against it on BBC2 at nine o'clock in the evening, with a schedule to be finalised," the statement read.
'Possibility to Undermine Trust'
The watchdog's statement stated: "Our investigation found that the film's lack of disclosure that the narrator's father held a position in the Hamas-controlled government was materially misleading.
"It meant that the viewers did not have critical information which may have been highly relevant to their judgment of the narrator and the details he presented.
"Confidence is at the center of the bond between a television network and its viewers, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the risk to erode the exceptionally strong degrees of confidence that audiences would have invested in a factual film from the broadcaster about the conflict in Gaza."
The film was pulled from the BBC's streaming service in the month of February after the boy's personal associations came to light, and in this past July an broadcaster's internal assessment found it breached the corporation's journalistic standards on accuracy.
A representative for the broadcaster said: "The Ofcom ruling is in agreement with the conclusions of Peter Johnston's review, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we accept the authority's determination in its entirety. We will adhere to the directive as soon as the schedule and language are finalised."
