The British broadcaster was found to have committed a "major breach" of broadcasting rules by not revealing that the presenter of a programme about the Gaza situation was the son of a Hamas representative, according to regulatory body Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The head of the BBC had previously apologised, noting there had been "a serious error in relation to accuracy".
The regulator has instructed the BBC to air a prime-time announcement about its findings.
"Given this constitutes a serious breach of our rules, we are ordering the BBC to transmit a statement of our determinations against it on BBC2 at 9pm, with a schedule to be confirmed," the statement read.
'Potential to Undermine Credibility'
The watchdog's announcement stated: "The inquiry we conducted concluded that the documentary's omission to reveal that the narrator's male guardian served in a position in the Hamas-run authority was materially misleading.
"It meant that the audience did not have vital facts which may have been highly relevant to their assessment of the presenter and the details he provided.
"Credibility is at the heart of the connection between a broadcaster and its public, especially for a national broadcasting corporation such as the public broadcaster.
"This failing had the possibility to erode the very considerable amounts of confidence that audiences would have put in a documentary produced by the BBC about the Gaza conflict."
The film was withdrawn from the online platform in last February after the boy's family links emerged, and in the month of July an corporation's own inquiry concluded it violated the broadcaster's journalistic standards on truthfulness.
A BBC spokesperson commented: "The Ofcom ruling is in agreement with the results of Peter Johnston's review, that there was a major oversight in the documentary in relation to the corporation's content standards on factual correctness, which corresponds to Rule 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we comply with the regulator's ruling in complete. We will follow the sanction as soon as the date and wording are confirmed."
