The BBC committed a "serious breach" of broadcasting rules by not revealing that the voice of a documentary about the Gaza situation was the offspring of a Hamas representative, as ruled by British broadcasting authority Ofcom.
An probe by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The BBC's director general had earlier expressed regret, saying there had been "a major oversight in relation to factual correctness".
The regulator has ordered the corporation to broadcast a evening statement about its findings.
"As this represents a major infringement of our code, we are instructing the BBC to broadcast a announcement of our findings against it on the BBC's second channel at 21:00, with a schedule to be determined," the regulator stated.
'Risk to Undermine Credibility'
The regulator's report declared: "Our probe concluded that the programme's lack of disclosure that the presenter's parent served in a role in the Hamas-run administration was significantly deceptive.
"It meant that the public did not have critical information which may have been extremely pertinent to their evaluation of the narrator and the information he shared.
"Credibility is at the heart of the bond 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 trust that the public would have placed in a documentary produced by the BBC about the conflict in Gaza."
The film was removed from the BBC's streaming service in February after the boy's familial connections were revealed, and in this past July an corporation's own inquiry found it breached the corporation's journalistic standards on accuracy.
A representative for the broadcaster stated: "The authority's determination is in accordance with the results of the internal assessment, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which reflects clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we comply with the regulator's ruling in complete. We will follow the directive as soon as the date and wording are confirmed."
