The public service broadcaster engaged in a "significant breach" of industry standards by omitting to mention that the presenter of a documentary about the Gaza conflict was the child of a Hamas official, as ruled by UK media regulator Ofcom.
An investigation by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "substantially inaccurate".
The chief executive of the broadcaster had already issued an apology, noting there had been "a significant failing in relation to truthfulness".
The authority has instructed the BBC to broadcast a peak-time statement about its decisions.
"Given this constitutes a major infringement of our regulations, we are instructing the broadcaster to broadcast a message of our findings against it on BBC2 at 9pm, with a date to be determined," the statement read.
'Potential to Erode Credibility'
The authority's announcement declared: "Our investigation concluded that the programme's omission to reveal that the voice's parent served in a post in the Hamas-administered government was materially misleading.
"This implied that the viewers did not have vital facts which may have been highly relevant to their judgment of the voice and the content he shared.
"Confidence is at the heart of the relationship between a media organization and its viewers, especially for a public service broadcaster such as the public broadcaster.
"This failing had the possibility to damage the exceptionally strong degrees of confidence that viewers would have put in a BBC factual programme about the Gaza conflict."
The film was pulled from iPlayer in last February after the presenter's family links emerged, and in the month of July an internal BBC review concluded it infringed the corporation's content policies on factual correctness.
A representative for the broadcaster said: "The Ofcom ruling is in agreement with the findings of the corporation's inquiry, that there was a significant failing in the programme in relation to the broadcaster's journalistic policies on accuracy, which reflects regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the authority's determination in complete. We will adhere to the directive as soon as the timing and wording are determined."
