The British broadcaster was found to have committed a "serious breach" of industry standards by failing to disclose that the presenter of a documentary about the Gaza situation was the child of a Hamas representative, as determined by UK media regulator Ofcom.
An probe by Ofcom into Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, noting there had been "a serious error in relation to factual correctness".
Ofcom has instructed the BBC to broadcast a evening declaration about its findings.
"Since this amounts to a major infringement of our rules, we are directing the BBC to transmit a announcement of our findings against it on the BBC's second channel at 21:00, with a date to be finalised," the regulator stated.
'Possibility to Undermine Trust'
The authority's announcement declared: "Our probe determined that the film's lack of disclosure that the narrator's father held a position in the Hamas-controlled administration was substantially inaccurate.
"It meant that the public did not have critical information which may have been very significant to their judgment of the presenter and the information he provided.
"Credibility is at the heart of the relationship between a television network and its audience, notably for a public service broadcaster such as the public broadcaster.
"This oversight had the possibility to erode the very considerable degrees of trust that viewers would have placed in a documentary produced by the BBC about the conflict in Gaza."
The programme was withdrawn from the BBC's streaming service in February after the boy's personal associations were revealed, and in the month of July an corporation's own inquiry determined it breached the broadcaster's content policies on factual correctness.
A BBC spokesperson stated: "The Ofcom ruling is in agreement with the results of the internal assessment, that there was a significant failing in the film in relation to the BBC's Editorial Guidelines on factual correctness, which reflects clause 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with the authority's determination in its entirety. We will follow the directive as soon as the schedule and wording are finalised."
