The British broadcaster committed a "serious breach" of media regulations by failing to disclose that the voice of a film about Gaza was the offspring of a Hamas administrator, as determined by UK media regulator Ofcom.
An probe by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the documentary was "materially misleading".
The head of the BBC had previously apologised, stating there had been "a major oversight in relation to truthfulness".
Ofcom has directed the BBC to broadcast a peak-time statement about its conclusions.
"As this represents a major infringement of our rules, we are ordering the BBC to broadcast a message of our findings against it on BBC Two at 9pm, with a timing to be confirmed," the statement read.
'Risk to Undermine Confidence'
The authority's statement stated: "Our probe concluded that the programme's lack of disclosure that the presenter's father occupied a role in the Hamas-controlled government was materially misleading.
"It meant that the public did not have vital facts which may have been very significant to their evaluation of the presenter and the details he provided.
"Credibility is at the core of the relationship between a broadcaster and its viewers, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This oversight had the possibility to undermine the exceptionally strong amounts of credibility that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The film was removed from iPlayer in the month of February after the narrator's familial connections were revealed, and in this past July an broadcaster's internal assessment determined it infringed the corporation's journalistic standards on truthfulness.
A representative for the broadcaster stated: "The regulator's decision is in line with the conclusions of the internal assessment, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on accuracy, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We expressed regret for this and we accept the regulator's ruling in its entirety. We will adhere to the directive as soon as the schedule and wording are finalised."
