The British broadcaster was found to have committed a "significant breach" of broadcasting rules by failing to disclose that the voice of a documentary about the Gaza conflict was the son of a Hamas representative, as determined by regulatory body Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The BBC's director general had earlier expressed regret, saying there had been "a major oversight in relation to truthfulness".
Ofcom has ordered the corporation to air a evening statement about its decisions.
"As this represents a major infringement of our code, we are directing the corporation to transmit 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 confirmed," the regulator stated.
'Risk to Undermine Credibility'
The regulator's announcement stated: "Our probe determined that the programme's failure to disclose that the voice's father held a position in the Hamas-run administration was materially misleading.
"This implied that the audience did not have essential details which may have been extremely pertinent to their assessment of the narrator and the content he presented.
"Confidence is at the core of the relationship between a media organization and its audience, particularly for a public service broadcaster such as the British Broadcasting Corporation.
"This oversight had the risk to damage the very considerable degrees of trust that viewers would have put in a factual film from the broadcaster about the conflict in Gaza."
The programme was removed from the online platform in February after the boy's family links came to light, and in the month of July an broadcaster's internal assessment determined it violated the organization's journalistic standards on truthfulness.
A corporation official commented: "The authority's determination is in agreement 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 truthfulness, which aligns with Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will comply with the sanction as soon as the date and wording are confirmed."
