The British broadcaster committed a "major breach" of broadcasting rules by failing to disclose that the voice of a film about the Gaza situation was the child of a Hamas administrator, as ruled by regulatory body Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The head of the BBC had previously apologised, noting there had been "a significant failing in relation to accuracy".
The authority has directed the BBC to transmit a evening statement about its conclusions.
"As this represents a major infringement of our rules, we are instructing the broadcaster to air a announcement of our conclusions against it on BBC Two at nine o'clock in the evening, with a timing to be determined," it said.
'Risk to Damage Trust'
The authority's statement stated: "The inquiry we conducted found that the film's failure to disclose that the presenter's father served in a position in the Hamas-controlled administration was significantly deceptive.
"It meant that the viewers did not have essential details which may have been highly relevant to their assessment of the narrator and the details he provided.
"Credibility is at the heart of the bond between a broadcaster and its audience, notably for a state-funded media outlet such as the public broadcaster.
"This oversight had the potential to undermine the significantly high levels of trust that audiences would have placed in a documentary produced by the BBC about the conflict in Gaza."
The programme was removed from the BBC's streaming service in last February after the boy's familial connections were revealed, and in the month of July an corporation's own inquiry determined it violated the organization's journalistic standards on factual correctness.
A BBC spokesperson said: "The Ofcom ruling is in line with the results of the internal assessment, that there was a major oversight in the programme in relation to the broadcaster's journalistic policies on accuracy, which corresponds to regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will adhere to the sanction as soon as the timing and language are finalised."
