The British broadcaster was found to have committed a "major breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza conflict was the child of a Hamas official, as determined by British broadcasting authority Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The chief executive of the broadcaster had previously apologised, stating there had been "a serious error in relation to factual correctness".
Ofcom has ordered the broadcaster to air a evening statement about its decisions.
"Since this amounts to a major infringement of our code, we are instructing the BBC to air a message of our determinations against it on BBC Two at 21:00, with a timing to be determined," it said.
'Possibility to Undermine Confidence'
The watchdog's announcement stated: "Our probe determined that the programme's omission to reveal that the narrator's parent held a role in the Hamas-controlled administration was materially misleading.
"This implied that the viewers did not have critical information which may have been very significant to their judgment of the voice and the details he provided.
"Confidence is at the core of the bond between a television network and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the potential to undermine the very considerable amounts of confidence that the public would have invested in a BBC factual programme about the conflict in Gaza."
The film was withdrawn from the BBC's streaming service in February after the presenter's family links were revealed, and in the month of July an broadcaster's internal assessment concluded it violated the organization's editorial guidelines on accuracy.
A corporation official stated: "The Ofcom ruling is in accordance with the findings of the internal assessment, that there was a major oversight in the film 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 adhere to the sanction as soon as the date and wording are finalised."
