The BBC was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the narrator of a programme about the Gaza situation was the son of a Hamas official, as ruled by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has concluded that the film was "materially misleading".
The chief executive of the broadcaster had previously apologised, noting there had been "a major oversight in relation to factual correctness".
The authority has ordered the broadcaster to transmit a evening announcement about its findings.
"Given this constitutes a major infringement of our code, we are directing the corporation to transmit a announcement of our findings against it on BBC Two at 9pm, with a timing to be finalised," it said.
'Potential to Erode Confidence'
The regulator's report declared: "The inquiry we conducted concluded that the film's omission to reveal that the narrator's father occupied a position in the Hamas-administered administration was substantially inaccurate.
"Consequently that the public did not have essential details which may have been extremely pertinent to their assessment of the voice and the details he presented.
"Trust is at the center of the connection between a television network and its viewers, notably for a national broadcasting corporation such as the public broadcaster.
"This oversight had the risk to undermine the very considerable levels of confidence that the public would have invested in a documentary produced by the BBC about the conflict in Gaza."
The documentary was pulled from the BBC's streaming service in the month of February after the boy's personal associations were revealed, and in the month of July an corporation's own inquiry concluded it infringed the broadcaster's editorial guidelines on accuracy.
A corporation official commented: "The authority's determination is in agreement with the results of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on truthfulness, which aligns with clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the authority's determination in its entirety. We will comply with the penalty as soon as the schedule and wording are finalised."
