The British broadcaster was found to have committed a "major breach" of industry standards by not revealing that the narrator of a film about Gaza was the offspring of a Hamas administrator, as ruled by British broadcasting authority Ofcom.
An investigation by the broadcasting watchdog into the documentary titled Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The chief executive of the broadcaster had earlier expressed regret, saying there had been "a serious error in relation to accuracy".
The authority has instructed the broadcaster to broadcast a evening statement about its decisions.
"As this represents a major infringement of our rules, we are directing the corporation to air a statement of our determinations against it on BBC Two at nine o'clock in the evening, with a date to be determined," the statement read.
'Risk to Damage Confidence'
The watchdog's statement stated: "Our investigation found that the documentary's lack of disclosure that the narrator's male guardian held a role in the Hamas-administered government was significantly deceptive.
"This implied that the audience did not have vital facts which may have been very significant to their assessment of the presenter and the content he shared.
"Trust is at the core of the bond between a media organization and its audience, notably for a national broadcasting corporation such as the BBC.
"This oversight had the possibility to undermine the exceptionally strong degrees of trust that audiences would have invested in a BBC factual programme about the Israel-Gaza war."
The documentary was withdrawn from the online platform in the month of February after the boy's familial connections came to light, and in July an corporation's own inquiry concluded it breached the corporation's journalistic standards on truthfulness.
A representative for the broadcaster said: "The authority's determination is in line with the conclusions of the internal assessment, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we comply with the regulator's ruling in its entirety. We will comply with the sanction as soon as the timing and wording are confirmed."
