The British broadcaster was found to have committed a "significant breach" of broadcasting rules by omitting to mention that the narrator of a documentary about the Gaza conflict was the child of a Hamas administrator, as determined by UK media regulator Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has concluded that the film was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, saying there had been "a significant failing in relation to accuracy".
The authority has directed the corporation to broadcast a peak-time announcement about its conclusions.
"As this represents a significant violation of our code, we are instructing the corporation to broadcast a message of our determinations against it on the BBC's second channel at 21:00, with a date to be finalised," the statement read.
'Risk to Erode Trust'
The authority's announcement declared: "Our investigation determined that the programme's omission to reveal that the voice's father held a role in the Hamas-run administration was materially misleading.
"It meant that the viewers did not have critical information which may have been extremely pertinent to their judgment of the narrator and the information he shared.
"Trust is at the center of the bond between a television network and its audience, particularly for a public service broadcaster such as the public broadcaster.
"This failing had the risk to damage the exceptionally strong amounts of confidence that viewers would have placed in a documentary produced by the BBC about the Gaza conflict."
The programme was removed from iPlayer in the month of February after the presenter's family links came to light, and in the month of July an internal BBC review found it infringed the organization's content policies on factual correctness.
A representative for the broadcaster said: "The Ofcom ruling is in accordance with the findings of the internal assessment, that there was a significant failing in the programme 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 accept Ofcom's decision in full. We will follow the sanction as soon as the date and language are determined."
