The British broadcaster was found to have committed a "serious breach" of media regulations by failing to disclose that the presenter of a film about Gaza was the son of a Hamas official, as determined by UK media regulator Ofcom.
An inquiry by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the film was "significantly deceptive".
The head of the BBC had earlier expressed regret, stating there had been "a serious error in relation to factual correctness".
The regulator has directed the BBC to transmit a evening statement about its decisions.
"Given this constitutes a significant violation of our rules, we are directing the BBC to transmit a statement of our findings against it on BBC2 at 21:00, with a schedule to be determined," it said.
'Risk to Damage Trust'
The authority's report declared: "Our probe determined that the documentary's omission to reveal that the narrator's father held a role in the Hamas-administered authority was materially misleading.
"Consequently that the viewers did not have essential details which may have been very significant to their assessment of the narrator and the content he shared.
"Credibility is at the heart of the connection between a broadcaster and its audience, notably for a national broadcasting corporation such as the BBC.
"This oversight had the potential to erode the exceptionally strong degrees of credibility that viewers would have put in a documentary produced by the BBC about the Israel-Gaza war."
The programme was pulled from iPlayer in February after the presenter's family links were revealed, and in this past July an corporation's own inquiry found it infringed the broadcaster's editorial guidelines on accuracy.
A representative for the broadcaster stated: "The authority's determination is in accordance with the results of the corporation's inquiry, that there was a significant failing in the documentary in relation to the broadcaster's journalistic policies on accuracy, which reflects Rule 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we accept Ofcom's decision in full. We will adhere to the directive as soon as the timing and wording are determined."
