The British broadcaster engaged in a "major breach" of industry standards by not revealing that the presenter of a documentary about Gaza was the offspring of a Hamas representative, as determined by UK media regulator Ofcom.
An investigation by the media regulator into Gaza: How to Survive a Warzone has found that the programme was "substantially inaccurate".
The chief executive of the broadcaster had previously apologised, stating there had been "a serious error in relation to accuracy".
The regulator has instructed the broadcaster to broadcast a peak-time announcement about its conclusions.
"As this represents a serious breach of our regulations, we are ordering the corporation to transmit a statement of our determinations against it on BBC2 at 21:00, with a date to be finalised," the statement read.
'Potential to Undermine Confidence'
The regulator's report declared: "Our investigation found that the programme's failure to disclose that the narrator's male guardian held a role in the Hamas-controlled authority was substantially inaccurate.
"Consequently that the viewers did not have essential details which may have been extremely pertinent to their judgment of the narrator and the information he presented.
"Trust is at the heart of the bond between a broadcaster and its viewers, notably for a state-funded media outlet such as the public broadcaster.
"This error had the possibility to undermine the exceptionally strong levels of trust that the public would have placed in a factual film from the broadcaster about the Gaza conflict."
The documentary was removed from the BBC's streaming service in the month of February after the boy's family links came to light, and in this past July an broadcaster's internal assessment determined it infringed the organization's journalistic standards 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 major oversight in the programme in relation to the corporation's content standards on factual correctness, which aligns with regulation 2.2 of the regulator's media standards.
"We expressed regret for this and we comply with Ofcom's decision in its entirety. We will comply with the directive as soon as the date and language are finalised."
