The British broadcaster committed a "major breach" of media regulations by not revealing that the narrator of a documentary about the Gaza situation was the child of a Hamas representative, as determined by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into Gaza: How to Survive a Warzone has found that the documentary was "materially misleading".
The chief executive of the broadcaster had already issued an apology, stating there had been "a serious error in relation to truthfulness".
Ofcom has directed the broadcaster to transmit a evening announcement about its conclusions.
"Given this constitutes a significant violation of our code, we are directing the BBC to broadcast a announcement of our determinations against it on the BBC's second channel at 21:00, with a date to be confirmed," it said.
'Potential to Damage Trust'
The regulator's report declared: "The inquiry we conducted determined that the film's omission to reveal that the narrator's parent held a role in the Hamas-administered administration was significantly deceptive.
"It meant that the viewers did not have essential details which may have been extremely pertinent to their assessment of the narrator and the information he shared.
"Confidence is at the heart of the bond between a television network and its viewers, notably for a state-funded media outlet such as the public broadcaster.
"This oversight had the risk to damage the very considerable levels of credibility that the public would have invested in a factual film from the broadcaster about the Gaza conflict."
The programme was withdrawn from the BBC's streaming service in the month of February after the presenter's family links came to light, and in July an internal BBC review concluded it breached the corporation's journalistic standards on truthfulness.
A corporation official stated: "The authority's determination is in agreement with the findings of the internal assessment, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on accuracy, which reflects Rule 2.2 of the authority's broadcasting regulations.
"We issued an apology for this and we comply with Ofcom's decision in complete. We will comply with the directive as soon as the date and wording are finalised."
