The British broadcaster committed a "serious breach" of broadcasting rules by failing to disclose that the voice of a programme about the Gaza situation was the son of a Hamas administrator, according to UK media regulator Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the film was "substantially inaccurate".
The BBC's director general had earlier expressed regret, stating there had been "a serious error in relation to accuracy".
The authority has instructed the corporation to transmit a peak-time statement about its findings.
"Since this amounts to a serious breach of our rules, we are ordering the corporation to transmit a announcement of our determinations against it on BBC Two at 21:00, with a timing to be confirmed," the regulator stated.
'Possibility to Erode Trust'
The authority's announcement declared: "The inquiry we conducted determined that the documentary's failure to disclose that the presenter's parent occupied a position in the Hamas-run government was materially misleading.
"Consequently that the viewers did not have vital facts which may have been highly relevant to their assessment of the presenter and the information he provided.
"Confidence is at the heart of the connection between a broadcaster and its audience, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the risk to erode the exceptionally strong degrees of credibility that audiences would have placed in a documentary produced by the BBC about the conflict in Gaza."
The documentary was removed from the BBC's streaming service in last February after the boy's familial connections came to light, and in the month of July an internal BBC review determined it violated the organization's journalistic standards on accuracy.
A corporation official commented: "The regulator's decision is in line with the results of the internal assessment, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with Ofcom's decision in its entirety. We will comply with the directive as soon as the timing and wording are determined."
