The public service broadcaster was found to have committed a "serious breach" of broadcasting rules by failing to disclose that the presenter of a programme about the Gaza situation was the offspring of a Hamas official, 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 film was "materially misleading".
The chief executive of the broadcaster had previously apologised, stating there had been "a major oversight in relation to truthfulness".
The authority has ordered the corporation to broadcast a evening announcement about its decisions.
"Since this amounts to a significant violation of our rules, we are directing the corporation to air a statement of our determinations against it on the BBC's second channel at 21:00, with a timing to be finalised," the statement read.
'Possibility to Damage Credibility'
The regulator's report said: "The inquiry we conducted concluded that the documentary's lack of disclosure that the narrator's male guardian held a position in the Hamas-run government was significantly deceptive.
"Consequently that the viewers did not have essential details which may have been highly relevant to their evaluation of the voice and the information he presented.
"Trust is at the center of the relationship between a broadcaster and its audience, especially for a state-funded media outlet such as the public broadcaster.
"This error had the risk to damage the significantly high degrees of credibility that audiences would have invested in a BBC factual programme about the Gaza conflict."
The documentary was removed from the BBC's streaming service in the month of February after the presenter's familial connections came to light, and in this past July an broadcaster's internal assessment determined it infringed the broadcaster's journalistic standards on accuracy.
A representative for the broadcaster commented: "The authority's determination is in line with the conclusions of the corporation's inquiry, that there was a significant failing in the programme in relation to the BBC's Editorial Guidelines on factual correctness, which corresponds to Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with the authority's determination in its entirety. We will adhere to the penalty as soon as the schedule and wording are finalised."
