The British broadcaster was found to have committed a "major breach" of broadcasting rules by failing to disclose that the presenter of a film about Gaza was the offspring of a Hamas administrator, as ruled by regulatory body Ofcom.
An probe by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The BBC's director general had already issued an apology, noting there had been "a serious error in relation to accuracy".
The regulator has directed the corporation to broadcast a prime-time statement about its conclusions.
"Given this constitutes a significant violation of our code, we are ordering the corporation to transmit a statement of our findings against it on the BBC's second channel at nine o'clock in the evening, with a schedule to be determined," the regulator stated.
'Potential to Erode Trust'
The regulator's announcement said: "The inquiry we conducted concluded that the film's lack of disclosure that the voice's male guardian held a post in the Hamas-administered government was significantly deceptive.
"It meant that the public did not have vital facts which may have been highly relevant to their evaluation of the narrator and the details he shared.
"Trust is at the core of the relationship between a media organization and its viewers, notably for a state-funded media outlet such as the public broadcaster.
"This oversight had the potential to damage the significantly high levels of confidence that audiences would have put in a factual film from the broadcaster about the Gaza conflict."
The programme was withdrawn from the online platform in last February after the presenter's personal associations emerged, and in July an broadcaster's internal assessment determined it violated the corporation's journalistic standards on accuracy.
A representative for the broadcaster said: "The regulator's decision is in agreement with the results of the corporation's inquiry, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which reflects regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with the regulator's ruling in full. We will comply with the sanction as soon as the schedule and language are finalised."
