The British broadcaster was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the voice of a documentary about the Gaza situation was the offspring of a Hamas administrator, as determined by regulatory body Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to factual correctness".
Ofcom has ordered the corporation to broadcast a peak-time declaration about its conclusions.
"Since this amounts to a significant violation of our regulations, we are directing the BBC to air a statement of our conclusions against it on the BBC's second channel at nine o'clock in the evening, with a timing to be determined," the statement read.
'Risk to Damage Credibility'
The authority's report stated: "Our probe found that the documentary's lack of disclosure that the voice's male guardian served in a role in the Hamas-controlled authority was substantially inaccurate.
"This implied that the viewers did not have critical information which may have been highly relevant to their evaluation of the presenter and the information he shared.
"Trust is at the center of the connection between a media organization and its public, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the risk to erode the exceptionally strong levels of credibility that viewers would have put in a BBC factual programme about the Gaza conflict."
The documentary was pulled from the online platform in the month of February after the boy's familial connections emerged, and in this past July an internal BBC review found it violated the broadcaster's editorial guidelines on accuracy.
A BBC spokesperson commented: "The Ofcom ruling is in agreement with the conclusions of the internal assessment, that there was a serious error in the programme in relation to the BBC's Editorial Guidelines on accuracy, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with the authority's determination in full. We will follow the sanction as soon as the date and wording are determined."
