The British broadcaster was found to have committed a "serious breach" of broadcasting rules by omitting to mention that the presenter of a programme about the Gaza conflict was the offspring of a Hamas representative, as determined by regulatory body Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a serious error in relation to accuracy".
The regulator has directed the broadcaster to air a evening statement about its conclusions.
"Given this constitutes a major infringement of our regulations, we are ordering the corporation to broadcast a statement of our conclusions against it on BBC Two at 21:00, with a date to be determined," it said.
'Potential to Damage Confidence'
The regulator's announcement stated: "The inquiry we conducted concluded that the documentary's omission to reveal that the voice's male guardian held a position in the Hamas-controlled government was substantially inaccurate.
"Consequently that the audience did not have vital facts which may have been highly relevant to their assessment of the presenter and the information he shared.
"Credibility is at the heart of the connection between a broadcaster and its audience, especially for a national broadcasting corporation such as the BBC.
"This failing had the potential to damage the exceptionally strong levels of confidence that audiences would have invested in a documentary produced by the BBC about the Gaza conflict."
The film was removed from the BBC's streaming service in February after the boy's familial connections emerged, and in the month of July an corporation's own inquiry determined it breached the broadcaster's content policies on factual correctness.
A representative for the broadcaster commented: "The authority's determination is in line with the findings of the internal assessment, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on accuracy, which aligns with Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with the authority's determination in full. We will adhere to the directive as soon as the timing and language are finalised."
