The public service broadcaster was found to have committed a "significant breach" of media regulations by failing to disclose that the voice of a film about the Gaza situation was the offspring of a Hamas administrator, as ruled by UK media regulator Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, noting there had been "a serious error in relation to factual correctness".
The authority has ordered the corporation to broadcast a evening statement about its findings.
"Given this constitutes a significant violation of our rules, we are directing the broadcaster to broadcast a announcement of our determinations against it on BBC2 at 21:00, with a date to be finalised," the statement read.
'Potential to Damage Credibility'
The authority's statement said: "Our investigation concluded that the documentary's omission to reveal that the presenter's father served in a role in the Hamas-administered authority was substantially inaccurate.
"It meant that the viewers did not have critical information which may have been highly relevant to their evaluation of the presenter and the details he shared.
"Trust is at the core of the connection between a media organization and its audience, particularly for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to damage the very considerable degrees of credibility that viewers would have put in a factual film from the broadcaster about the Gaza conflict."
The documentary was withdrawn from the BBC's streaming service in the month of February after the boy's familial connections were revealed, and in the month of July an broadcaster's internal assessment determined it breached the broadcaster's journalistic standards on accuracy.
A corporation official commented: "The Ofcom ruling is in agreement 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 accuracy, which reflects Rule 2.2 of the regulator's media standards.
"We expressed regret for this and we accept the regulator's ruling in full. We will follow the penalty as soon as the schedule and wording are confirmed."
