The BBC was found to have committed a "significant breach" of media regulations by omitting to mention that the voice of a film about the Gaza situation was the offspring of a Hamas representative, as determined by British broadcasting authority Ofcom.
An inquiry by the media regulator into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The head of the BBC had already issued an apology, noting there had been "a significant failing in relation to accuracy".
The authority has instructed the BBC to broadcast a prime-time declaration about its findings.
"Given this constitutes a major infringement of our code, we are instructing the corporation to broadcast a message of our findings against it on BBC Two at 21:00, with a schedule to be confirmed," the statement read.
'Risk to Undermine Trust'
The regulator's statement declared: "Our investigation determined that the programme's omission to reveal that the narrator's father served in a post in the Hamas-controlled government was significantly deceptive.
"It meant that the audience did not have essential details which may have been highly relevant to their evaluation of the voice and the content he presented.
"Credibility is at the center of the bond between a media organization and its public, especially for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the potential to damage the very considerable levels of trust that audiences would have put in a factual film from the broadcaster about the conflict in Gaza."
The programme was removed from iPlayer in last February after the boy's personal associations came to light, and in the month of July an internal BBC review concluded it violated the corporation's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The authority's determination is in accordance with the results of the internal assessment, that there was a serious error in the film in relation to the broadcaster's journalistic policies on factual correctness, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with Ofcom's decision in full. We will comply with the directive as soon as the schedule and language are determined."
