The British broadcaster committed a "major breach" of broadcasting rules by failing to disclose that the voice of a programme about Gaza was the offspring of a Hamas representative, as determined by British broadcasting authority Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the documentary was "materially misleading".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a major oversight in relation to factual correctness".
The authority has directed the BBC to transmit a peak-time statement about its decisions.
"Given this constitutes a significant violation of our code, we are ordering the broadcaster to broadcast a message of our determinations against it on BBC2 at nine o'clock in the evening, with a date to be confirmed," the statement read.
'Potential to Damage Credibility'
The authority's statement declared: "Our investigation concluded that the documentary's failure to disclose that the narrator's parent held a post in the Hamas-run administration was substantially inaccurate.
"Consequently that the public did not have vital facts which may have been highly relevant to their judgment of the presenter and the content he shared.
"Confidence is at the center of the connection between a television network and its audience, particularly for a state-funded media outlet such as the BBC.
"This error had the possibility to erode the significantly high degrees of credibility that viewers would have placed in a factual film from the broadcaster about the conflict in Gaza."
The documentary was pulled from the BBC's streaming service in February after the boy's family links came to light, and in this past July an broadcaster's internal assessment concluded it violated the organization's content policies on accuracy.
A representative for the broadcaster stated: "The authority's determination is in line with the findings of the corporation's inquiry, that there was a major oversight in the documentary in relation to the broadcaster's journalistic policies on factual correctness, which corresponds to clause 2.2 of the regulator's media standards.
"We expressed regret for this and we agree with the authority's determination in its entirety. We will follow the directive as soon as the schedule and language are finalised."
