The public service broadcaster was found to have committed a "serious breach" of media regulations by not revealing that the presenter of a documentary about Gaza was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the documentary was "significantly deceptive".
The head of the BBC had earlier expressed regret, saying there had been "a major oversight in relation to factual correctness".
Ofcom has instructed the BBC to transmit a evening statement about its findings.
"Since this amounts to a significant violation of our code, we are ordering the BBC to transmit a statement of our findings against it on BBC Two at 21:00, with a date to be confirmed," the statement read.
'Risk to Erode Confidence'
The watchdog's report declared: "The inquiry we conducted concluded that the programme's failure to disclose that the presenter's parent occupied a role in the Hamas-controlled government was significantly deceptive.
"It meant that the audience did not have vital facts which may have been highly relevant to their assessment of the narrator and the details he shared.
"Confidence is at the core of the bond between a television network and its audience, especially for a state-funded media outlet such as the public broadcaster.
"This oversight had the potential to undermine the exceptionally strong amounts of confidence that the public would have put in a factual film from the broadcaster about the conflict in Gaza."
The film was removed from iPlayer in February after the boy's familial connections emerged, and in the month of July an broadcaster's internal assessment found it infringed the corporation's content policies on factual correctness.
A corporation official said: "The authority's determination is in agreement with the results of the corporation's inquiry, that there was a serious error in the documentary in relation to the corporation's content standards on accuracy, which corresponds to regulation 2.2 of the regulator's media standards.
"We issued an apology for this and we agree with the authority's determination in full. We will follow the sanction as soon as the date and wording are determined."
