The British broadcaster was found to have committed a "significant breach" of industry standards by omitting to mention that the narrator of a programme about the Gaza conflict was the offspring of a Hamas representative, as ruled by UK media regulator Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has found that the programme was "significantly deceptive".
The chief executive of the broadcaster had already issued an apology, noting there had been "a significant failing in relation to factual correctness".
Ofcom has directed the corporation to broadcast a peak-time statement about its decisions.
"Given this constitutes a significant violation of our regulations, we are ordering the corporation to broadcast a statement of our determinations against it on BBC Two at 21:00, with a schedule to be confirmed," it said.
'Possibility to Erode Credibility'
The watchdog's report stated: "The inquiry we conducted determined that the programme's failure to disclose that the voice's father served in a post in the Hamas-administered administration was materially misleading.
"It meant that the audience did not have vital facts which may have been extremely pertinent to their evaluation of the presenter and the details he presented.
"Confidence is at the heart of the connection between a television network and its public, especially for a national broadcasting corporation such as the British Broadcasting Corporation.
"This failing had the risk to erode the significantly high degrees of confidence that audiences would have put in a BBC factual programme about the Israel-Gaza war."
The film was withdrawn from the BBC's streaming service in February after the presenter's familial connections emerged, and in this past July an broadcaster's internal assessment determined it violated the corporation's content policies on accuracy.
A representative for the broadcaster stated: "The Ofcom ruling is in accordance with the results of the internal assessment, that there was a major oversight in the documentary in relation to the broadcaster's journalistic policies on accuracy, which corresponds to clause 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with Ofcom's decision in its entirety. We will follow the sanction as soon as the timing and language are finalised."
