The public service broadcaster was found to have committed a "significant breach" of media regulations by not revealing that the presenter of a programme about the Gaza situation was the son of a Hamas official, as determined by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The head of the BBC had already issued an apology, saying there had been "a serious error in relation to accuracy".
The authority has ordered the BBC to transmit a evening declaration about its decisions.
"As this represents a major infringement of our rules, we are directing the broadcaster to transmit a statement of our findings against it on BBC Two at 21:00, with a schedule to be determined," the regulator stated.
'Possibility to Damage Trust'
The authority's report stated: "Our probe concluded that the programme's lack of disclosure that the presenter's father occupied a role in the Hamas-controlled administration was significantly deceptive.
"Consequently that the audience did not have essential details which may have been very significant to their judgment of the presenter and the details he presented.
"Confidence is at the core of the bond between a television network and its viewers, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the possibility to erode the exceptionally strong levels of credibility that the public would have invested in a BBC factual programme about the Gaza conflict."
The programme was pulled from iPlayer in the month of February after the presenter's familial connections emerged, and in the month of July an broadcaster's internal assessment found it violated the organization's journalistic standards on accuracy.
A corporation official commented: "The regulator's decision is in agreement with the results of the internal assessment, that there was a major oversight in the documentary in relation to the BBC's Editorial Guidelines on factual correctness, which corresponds to clause 2.2 of Ofcom's Broadcasting Code.
"We issued an apology for this and we accept Ofcom's decision in full. We will comply with the directive as soon as the timing and wording are finalised."
