The British broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the presenter of a documentary about the Gaza conflict was the child of a Hamas official, as determined by British broadcasting authority Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "materially misleading".
The BBC's director general had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The authority has ordered the broadcaster to broadcast a peak-time declaration about its findings.
"Given this constitutes a serious breach of our regulations, we are directing the corporation to transmit a statement of our determinations against it on BBC Two at 9pm, with a date to be finalised," the regulator stated.
'Possibility to Damage Confidence'
The authority's report said: "The inquiry we conducted found that the documentary's lack of disclosure that the narrator's father held a post in the Hamas-administered authority was substantially inaccurate.
"Consequently that the public did not have essential details which may have been very significant to their assessment of the presenter and the details he presented.
"Confidence is at the center of the connection between a media organization and its viewers, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This failing had the possibility to erode the significantly high amounts of credibility that the public would have placed in a factual film from the broadcaster about the conflict in Gaza."
The documentary was removed from the BBC's streaming service in the month of February after the boy's personal associations were revealed, and in July an broadcaster's internal assessment found it violated the organization's journalistic standards on accuracy.
A BBC spokesperson stated: "The authority's determination is in line with the conclusions of Peter Johnston's review, that there was a significant failing in the documentary in relation to the BBC's Editorial Guidelines on truthfulness, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will follow the directive as soon as the timing and wording are finalised."
